+
+1 Overview
+**********
+
+GNU Wget is a free utility for non-interactive download of files from
+the Web. It supports HTTP, HTTPS, and FTP protocols, as well as
+retrieval through HTTP proxies.
+
+ This chapter is a partial overview of Wget's features.
+
+ * Wget is non-interactive, meaning that it can work in the
+ background, while the user is not logged on. This allows you to
+ start a retrieval and disconnect from the system, letting Wget
+ finish the work. By contrast, most of the Web browsers require
+ constant user's presence, which can be a great hindrance when
+ transferring a lot of data.
+
+ * Wget can follow links in HTML and XHTML pages and create local
+ versions of remote web sites, fully recreating the directory
+ structure of the original site. This is sometimes referred to as
+ "recursive downloading." While doing that, Wget respects the
+ Robot Exclusion Standard (`/robots.txt'). Wget can be instructed
+ to convert the links in downloaded HTML files to the local files
+ for offline viewing.
+
+ * File name wildcard matching and recursive mirroring of directories
+ are available when retrieving via FTP. Wget can read the
+ time-stamp information given by both HTTP and FTP servers, and
+ store it locally. Thus Wget can see if the remote file has
+ changed since last retrieval, and automatically retrieve the new
+ version if it has. This makes Wget suitable for mirroring of FTP
+ sites, as well as home pages.
+
+ * Wget has been designed for robustness over slow or unstable network
+ connections; if a download fails due to a network problem, it will
+ keep retrying until the whole file has been retrieved. If the
+ server supports regetting, it will instruct the server to continue
+ the download from where it left off.
+
+ * Wget supports proxy servers, which can lighten the network load,
+ speed up retrieval and provide access behind firewalls. However,
+ if you are behind a firewall that requires that you use a socks
+ style gateway, you can get the socks library and build Wget with
+ support for socks. Wget uses the passive FTP downloading by
+ default, active FTP being an option.
+
+ * Wget supports IP version 6, the next generation of IP. IPv6 is
+ autodetected at compile-time, and can be disabled at either build
+ or run time. Binaries built with IPv6 support work well in both
+ IPv4-only and dual family environments.
+
+ * Built-in features offer mechanisms to tune which links you wish to
+ follow (*note Following Links::).
+
+ * The progress of individual downloads is traced using a progress
+ gauge. Interactive downloads are tracked using a
+ "thermometer"-style gauge, whereas non-interactive ones are traced
+ with dots, each dot representing a fixed amount of data received
+ (1KB by default). Either gauge can be customized to your
+ preferences.
+
+ * Most of the features are fully configurable, either through
+ command line options, or via the initialization file `.wgetrc'
+ (*note Startup File::). Wget allows you to define "global"
+ startup files (`/usr/local/etc/wgetrc' by default) for site
+ settings.
+
+ * Finally, GNU Wget is free software. This means that everyone may
+ use it, redistribute it and/or modify it under the terms of the
+ GNU General Public License, as published by the Free Software
+ Foundation (*note Copying::).

+2 Invoking
+**********
+
+By default, Wget is very simple to invoke. The basic syntax is:
+
+ wget [OPTION]... [URL]...
+
+ Wget will simply download all the URLs specified on the command
+line. URL is a "Uniform Resource Locator", as defined below.
+
+ However, you may wish to change some of the default parameters of
+Wget. You can do it two ways: permanently, adding the appropriate
+command to `.wgetrc' (*note Startup File::), or specifying it on the
+command line.

+
+File: wget.info, Node: URL Format, Next: Option Syntax, Up: Invoking
+
+2.1 URL Format
+==============
+
+"URL" is an acronym for Uniform Resource Locator. A uniform resource
+locator is a compact string representation for a resource available via
+the Internet. Wget recognizes the URL syntax as per RFC1738. This is
+the most widely used form (square brackets denote optional parts):
+
+ http://host[:port]/directory/file
+ ftp://host[:port]/directory/file
+
+ You can also encode your username and password within a URL:
+
+ ftp://user:password@host/path
+ http://user:password@host/path
+
+ Either USER or PASSWORD, or both, may be left out. If you leave out
+either the HTTP username or password, no authentication will be sent.
+If you leave out the FTP username, `anonymous' will be used. If you
+leave out the FTP password, your email address will be supplied as a
+default password.(1)
+
+ *Important Note*: if you specify a password-containing URL on the
+command line, the username and password will be plainly visible to all
+users on the system, by way of `ps'. On multi-user systems, this is a
+big security risk. To work around it, use `wget -i -' and feed the
+URLs to Wget's standard input, each on a separate line, terminated by
+`C-d'.
+
+ You can encode unsafe characters in a URL as `%xy', `xy' being the
+hexadecimal representation of the character's ASCII value. Some common
+unsafe characters include `%' (quoted as `%25'), `:' (quoted as `%3A'),
+and `@' (quoted as `%40'). Refer to RFC1738 for a comprehensive list
+of unsafe characters.
+
+ Wget also supports the `type' feature for FTP URLs. By default, FTP
+documents are retrieved in the binary mode (type `i'), which means that
+they are downloaded unchanged. Another useful mode is the `a'
+("ASCII") mode, which converts the line delimiters between the
+different operating systems, and is thus useful for text files. Here
+is an example:
+
+ ftp://host/directory/file;type=a
+
+ Two alternative variants of URL specification are also supported,
+because of historical (hysterical?) reasons and their widespreaded use.
+
+ FTP-only syntax (supported by `NcFTP'):
+ host:/dir/file
+
+ HTTP-only syntax (introduced by `Netscape'):
+ host[:port]/dir/file
+
+ These two alternative forms are deprecated, and may cease being
+supported in the future.
+
+ If you do not understand the difference between these notations, or
+do not know which one to use, just use the plain ordinary format you use
+with your favorite browser, like `Lynx' or `Netscape'.
+
+ ---------- Footnotes ----------
+
+ (1) If you have a `.netrc' file in your home directory, password
+will also be searched for there.
+
+
+File: wget.info, Node: Option Syntax, Next: Basic Startup Options, Prev: URL Format, Up: Invoking
+
+2.2 Option Syntax
+=================
+
+Since Wget uses GNU getopt to process command-line arguments, every
+option has a long form along with the short one. Long options are more
+convenient to remember, but take time to type. You may freely mix
+different option styles, or specify options after the command-line
+arguments. Thus you may write:
+
+ wget -r --tries=10 http://fly.srk.fer.hr/ -o log
+
+ The space between the option accepting an argument and the argument
+may be omitted. Instead `-o log' you can write `-olog'.
+
+ You may put several options that do not require arguments together,
+like:
+
+ wget -drc URL
+
+ This is a complete equivalent of:
+
+ wget -d -r -c URL
+
+ Since the options can be specified after the arguments, you may
+terminate them with `--'. So the following will try to download URL
+`-x', reporting failure to `log':
+
+ wget -o log -- -x
+
+ The options that accept comma-separated lists all respect the
+convention that specifying an empty list clears its value. This can be
+useful to clear the `.wgetrc' settings. For instance, if your `.wgetrc'
+sets `exclude_directories' to `/cgi-bin', the following example will
+first reset it, and then set it to exclude `/~nobody' and `/~somebody'.
+You can also clear the lists in `.wgetrc' (*note Wgetrc Syntax::).
+
+ wget -X '' -X /~nobody,/~somebody
+
+ Most options that do not accept arguments are "boolean" options, so
+named because their state can be captured with a yes-or-no ("boolean")
+variable. For example, `--follow-ftp' tells Wget to follow FTP links
+from HTML files and, on the other hand, `--no-glob' tells it not to
+perform file globbing on FTP URLs. A boolean option is either
+"affirmative" or "negative" (beginning with `--no'). All such options
+share several properties.
+
+ Unless stated otherwise, it is assumed that the default behavior is
+the opposite of what the option accomplishes. For example, the
+documented existence of `--follow-ftp' assumes that the default is to
+_not_ follow FTP links from HTML pages.
+
+ Affirmative options can be negated by prepending the `--no-' to the
+option name; negative options can be negated by omitting the `--no-'
+prefix. This might seem superfluous--if the default for an affirmative
+option is to not do something, then why provide a way to explicitly
+turn it off? But the startup file may in fact change the default. For
+instance, using `follow_ftp = off' in `.wgetrc' makes Wget _not_ follow
+FTP links by default, and using `--no-follow-ftp' is the only way to
+restore the factory default from the command line.

+
+2.3 Basic Startup Options
+=========================
+
+`-V'
+`--version'
+ Display the version of Wget.
+
+`-h'
+`--help'
+ Print a help message describing all of Wget's command-line options.
+
+`-b'
+`--background'
+ Go to background immediately after startup. If no output file is
+ specified via the `-o', output is redirected to `wget-log'.
+
+`-e COMMAND'
+`--execute COMMAND'
+ Execute COMMAND as if it were a part of `.wgetrc' (*note Startup
+ File::). A command thus invoked will be executed _after_ the
+ commands in `.wgetrc', thus taking precedence over them. If you
+ need to specify more than one wgetrc command, use multiple
+ instances of `-e'.
+
+
+
+File: wget.info, Node: Logging and Input File Options, Next: Download Options, Prev: Basic Startup Options, Up: Invoking
+
+2.4 Logging and Input File Options
+==================================
+
+`-o LOGFILE'
+`--output-file=LOGFILE'
+ Log all messages to LOGFILE. The messages are normally reported
+ to standard error.
+
+`-a LOGFILE'
+`--append-output=LOGFILE'
+ Append to LOGFILE. This is the same as `-o', only it appends to
+ LOGFILE instead of overwriting the old log file. If LOGFILE does
+ not exist, a new file is created.
+
+`-d'
+`--debug'
+ Turn on debug output, meaning various information important to the
+ developers of Wget if it does not work properly. Your system
+ administrator may have chosen to compile Wget without debug
+ support, in which case `-d' will not work. Please note that
+ compiling with debug support is always safe--Wget compiled with
+ the debug support will _not_ print any debug info unless requested
+ with `-d'. *Note Reporting Bugs::, for more information on how to
+ use `-d' for sending bug reports.
+
+`-q'
+`--quiet'
+ Turn off Wget's output.
+
+`-v'
+`--verbose'
+ Turn on verbose output, with all the available data. The default
+ output is verbose.
+
+`-nv'
+`--no-verbose'
+ Turn off verbose without being completely quiet (use `-q' for
+ that), which means that error messages and basic information still
+ get printed.
+
+`-i FILE'
+`--input-file=FILE'
+ Read URLs from FILE. If `-' is specified as FILE, URLs are read
+ from the standard input. (Use `./-' to read from a file literally
+ named `-'.)
+
+ If this function is used, no URLs need be present on the command
+ line. If there are URLs both on the command line and in an input
+ file, those on the command lines will be the first ones to be
+ retrieved. The FILE need not be an HTML document (but no harm if
+ it is)--it is enough if the URLs are just listed sequentially.
+
+ However, if you specify `--force-html', the document will be
+ regarded as `html'. In that case you may have problems with
+ relative links, which you can solve either by adding `<base
+ href="URL">' to the documents or by specifying `--base=URL' on the
+ command line.
+
+`-F'
+`--force-html'
+ When input is read from a file, force it to be treated as an HTML
+ file. This enables you to retrieve relative links from existing
+ HTML files on your local disk, by adding `<base href="URL">' to
+ HTML, or using the `--base' command-line option.
+
+`-B URL'
+`--base=URL'
+ Prepends URL to relative links read from the file specified with
+ the `-i' option.
+
+
+File: wget.info, Node: Download Options, Next: Directory Options, Prev: Logging and Input File Options, Up: Invoking
+
+2.5 Download Options
+====================
+
+`--bind-address=ADDRESS'
+ When making client TCP/IP connections, bind to ADDRESS on the
+ local machine. ADDRESS may be specified as a hostname or IP
+ address. This option can be useful if your machine is bound to
+ multiple IPs.
+
+`-t NUMBER'
+`--tries=NUMBER'
+ Set number of retries to NUMBER. Specify 0 or `inf' for infinite
+ retrying. The default is to retry 20 times, with the exception of
+ fatal errors like "connection refused" or "not found" (404), which
+ are not retried.
+
+`-O FILE'
+`--output-document=FILE'
+ The documents will not be written to the appropriate files, but all
+ will be concatenated together and written to FILE. If `-' is used
+ as FILE, documents will be printed to standard output, disabling
+ link conversion. (Use `./-' to print to a file literally named
+ `-'.)
+
+ Note that a combination with `-k' is only well-defined for
+ downloading a single document.
+
+`-nc'
+`--no-clobber'
+ If a file is downloaded more than once in the same directory,
+ Wget's behavior depends on a few options, including `-nc'. In
+ certain cases, the local file will be "clobbered", or overwritten,
+ upon repeated download. In other cases it will be preserved.
+
+ When running Wget without `-N', `-nc', or `-r', downloading the
+ same file in the same directory will result in the original copy
+ of FILE being preserved and the second copy being named `FILE.1'.
+ If that file is downloaded yet again, the third copy will be named
+ `FILE.2', and so on. When `-nc' is specified, this behavior is
+ suppressed, and Wget will refuse to download newer copies of
+ `FILE'. Therefore, "`no-clobber'" is actually a misnomer in this
+ mode--it's not clobbering that's prevented (as the numeric
+ suffixes were already preventing clobbering), but rather the
+ multiple version saving that's prevented.
+
+ When running Wget with `-r', but without `-N' or `-nc',
+ re-downloading a file will result in the new copy simply
+ overwriting the old. Adding `-nc' will prevent this behavior,
+ instead causing the original version to be preserved and any newer
+ copies on the server to be ignored.
+
+ When running Wget with `-N', with or without `-r', the decision as
+ to whether or not to download a newer copy of a file depends on
+ the local and remote timestamp and size of the file (*note
+ Time-Stamping::). `-nc' may not be specified at the same time as
+ `-N'.
+
+ Note that when `-nc' is specified, files with the suffixes `.html'
+ or `.htm' will be loaded from the local disk and parsed as if they
+ had been retrieved from the Web.
+
+`-c'
+`--continue'
+ Continue getting a partially-downloaded file. This is useful when
+ you want to finish up a download started by a previous instance of
+ Wget, or by another program. For instance:
+
+ wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z
+
+ If there is a file named `ls-lR.Z' in the current directory, Wget
+ will assume that it is the first portion of the remote file, and
+ will ask the server to continue the retrieval from an offset equal
+ to the length of the local file.
+
+ Note that you don't need to specify this option if you just want
+ the current invocation of Wget to retry downloading a file should
+ the connection be lost midway through. This is the default
+ behavior. `-c' only affects resumption of downloads started
+ _prior_ to this invocation of Wget, and whose local files are
+ still sitting around.
+
+ Without `-c', the previous example would just download the remote
+ file to `ls-lR.Z.1', leaving the truncated `ls-lR.Z' file alone.
+
+ Beginning with Wget 1.7, if you use `-c' on a non-empty file, and
+ it turns out that the server does not support continued
+ downloading, Wget will refuse to start the download from scratch,
+ which would effectively ruin existing contents. If you really
+ want the download to start from scratch, remove the file.
+
+ Also beginning with Wget 1.7, if you use `-c' on a file which is of
+ equal size as the one on the server, Wget will refuse to download
+ the file and print an explanatory message. The same happens when
+ the file is smaller on the server than locally (presumably because
+ it was changed on the server since your last download
+ attempt)--because "continuing" is not meaningful, no download
+ occurs.
+
+ On the other side of the coin, while using `-c', any file that's
+ bigger on the server than locally will be considered an incomplete
+ download and only `(length(remote) - length(local))' bytes will be
+ downloaded and tacked onto the end of the local file. This
+ behavior can be desirable in certain cases--for instance, you can
+ use `wget -c' to download just the new portion that's been
+ appended to a data collection or log file.
+
+ However, if the file is bigger on the server because it's been
+ _changed_, as opposed to just _appended_ to, you'll end up with a
+ garbled file. Wget has no way of verifying that the local file is
+ really a valid prefix of the remote file. You need to be
+ especially careful of this when using `-c' in conjunction with
+ `-r', since every file will be considered as an "incomplete
+ download" candidate.
+
+ Another instance where you'll get a garbled file if you try to use
+ `-c' is if you have a lame HTTP proxy that inserts a "transfer
+ interrupted" string into the local file. In the future a
+ "rollback" option may be added to deal with this case.
+
+ Note that `-c' only works with FTP servers and with HTTP servers
+ that support the `Range' header.
+
+`--progress=TYPE'
+ Select the type of the progress indicator you wish to use. Legal
+ indicators are "dot" and "bar".
+
+ The "bar" indicator is used by default. It draws an ASCII progress
+ bar graphics (a.k.a "thermometer" display) indicating the status of
+ retrieval. If the output is not a TTY, the "dot" bar will be used
+ by default.
+
+ Use `--progress=dot' to switch to the "dot" display. It traces
+ the retrieval by printing dots on the screen, each dot
+ representing a fixed amount of downloaded data.
+
+ When using the dotted retrieval, you may also set the "style" by
+ specifying the type as `dot:STYLE'. Different styles assign
+ different meaning to one dot. With the `default' style each dot
+ represents 1K, there are ten dots in a cluster and 50 dots in a
+ line. The `binary' style has a more "computer"-like
+ orientation--8K dots, 16-dots clusters and 48 dots per line (which
+ makes for 384K lines). The `mega' style is suitable for
+ downloading very large files--each dot represents 64K retrieved,
+ there are eight dots in a cluster, and 48 dots on each line (so
+ each line contains 3M).
+
+ Note that you can set the default style using the `progress'
+ command in `.wgetrc'. That setting may be overridden from the
+ command line. The exception is that, when the output is not a
+ TTY, the "dot" progress will be favored over "bar". To force the
+ bar output, use `--progress=bar:force'.
+
+`-N'
+`--timestamping'
+ Turn on time-stamping. *Note Time-Stamping::, for details.
+
+`-S'
+`--server-response'
+ Print the headers sent by HTTP servers and responses sent by FTP
+ servers.
+
+`--spider'
+ When invoked with this option, Wget will behave as a Web "spider",
+ which means that it will not download the pages, just check that
+ they are there. For example, you can use Wget to check your
+ bookmarks:
+
+ wget --spider --force-html -i bookmarks.html
+
+ This feature needs much more work for Wget to get close to the
+ functionality of real web spiders.
+
+`-T seconds'
+`--timeout=SECONDS'
+ Set the network timeout to SECONDS seconds. This is equivalent to
+ specifying `--dns-timeout', `--connect-timeout', and
+ `--read-timeout', all at the same time.
+
+ When interacting with the network, Wget can check for timeout and
+ abort the operation if it takes too long. This prevents anomalies
+ like hanging reads and infinite connects. The only timeout
+ enabled by default is a 900-second read timeout. Setting a
+ timeout to 0 disables it altogether. Unless you know what you are
+ doing, it is best not to change the default timeout settings.
+
+ All timeout-related options accept decimal values, as well as
+ subsecond values. For example, `0.1' seconds is a legal (though
+ unwise) choice of timeout. Subsecond timeouts are useful for
+ checking server response times or for testing network latency.
+
+`--dns-timeout=SECONDS'
+ Set the DNS lookup timeout to SECONDS seconds. DNS lookups that
+ don't complete within the specified time will fail. By default,
+ there is no timeout on DNS lookups, other than that implemented by
+ system libraries.
+
+`--connect-timeout=SECONDS'
+ Set the connect timeout to SECONDS seconds. TCP connections that
+ take longer to establish will be aborted. By default, there is no
+ connect timeout, other than that implemented by system libraries.
+
+`--read-timeout=SECONDS'
+ Set the read (and write) timeout to SECONDS seconds. The "time"
+ of this timeout refers "idle time": if, at any point in the
+ download, no data is received for more than the specified number
+ of seconds, reading fails and the download is restarted. This
+ option does not directly affect the duration of the entire
+ download.
+
+ Of course, the remote server may choose to terminate the connection
+ sooner than this option requires. The default read timeout is 900
+ seconds.
+
+`--limit-rate=AMOUNT'
+ Limit the download speed to AMOUNT bytes per second. Amount may
+ be expressed in bytes, kilobytes with the `k' suffix, or megabytes
+ with the `m' suffix. For example, `--limit-rate=20k' will limit
+ the retrieval rate to 20KB/s. This is useful when, for whatever
+ reason, you don't want Wget to consume the entire available
+ bandwidth.
+
+ This option allows the use of decimal numbers, usually in
+ conjunction with power suffixes; for example, `--limit-rate=2.5k'
+ is a legal value.
+
+ Note that Wget implements the limiting by sleeping the appropriate
+ amount of time after a network read that took less time than
+ specified by the rate. Eventually this strategy causes the TCP
+ transfer to slow down to approximately the specified rate.
+ However, it may take some time for this balance to be achieved, so
+ don't be surprised if limiting the rate doesn't work well with
+ very small files.
+
+`-w SECONDS'
+`--wait=SECONDS'
+ Wait the specified number of seconds between the retrievals. Use
+ of this option is recommended, as it lightens the server load by
+ making the requests less frequent. Instead of in seconds, the
+ time can be specified in minutes using the `m' suffix, in hours
+ using `h' suffix, or in days using `d' suffix.
+
+ Specifying a large value for this option is useful if the network
+ or the destination host is down, so that Wget can wait long enough
+ to reasonably expect the network error to be fixed before the
+ retry.
+
+`--waitretry=SECONDS'
+ If you don't want Wget to wait between _every_ retrieval, but only
+ between retries of failed downloads, you can use this option.
+ Wget will use "linear backoff", waiting 1 second after the first
+ failure on a given file, then waiting 2 seconds after the second
+ failure on that file, up to the maximum number of SECONDS you
+ specify. Therefore, a value of 10 will actually make Wget wait up
+ to (1 + 2 + ... + 10) = 55 seconds per file.
+
+ Note that this option is turned on by default in the global
+ `wgetrc' file.
+
+`--random-wait'
+ Some web sites may perform log analysis to identify retrieval
+ programs such as Wget by looking for statistically significant
+ similarities in the time between requests. This option causes the
+ time between requests to vary between 0 and 2 * WAIT seconds,
+ where WAIT was specified using the `--wait' option, in order to
+ mask Wget's presence from such analysis.
+
+ A recent article in a publication devoted to development on a
+ popular consumer platform provided code to perform this analysis
+ on the fly. Its author suggested blocking at the class C address
+ level to ensure automated retrieval programs were blocked despite
+ changing DHCP-supplied addresses.
+
+ The `--random-wait' option was inspired by this ill-advised
+ recommendation to block many unrelated users from a web site due
+ to the actions of one.
+
+`--no-proxy'
+ Don't use proxies, even if the appropriate `*_proxy' environment
+ variable is defined.
+
+ For more information about the use of proxies with Wget, *Note
+ Proxies::.
+
+`-Q QUOTA'
+`--quota=QUOTA'
+ Specify download quota for automatic retrievals. The value can be
+ specified in bytes (default), kilobytes (with `k' suffix), or
+ megabytes (with `m' suffix).
+
+ Note that quota will never affect downloading a single file. So
+ if you specify `wget -Q10k ftp://wuarchive.wustl.edu/ls-lR.gz',
+ all of the `ls-lR.gz' will be downloaded. The same goes even when
+ several URLs are specified on the command-line. However, quota is
+ respected when retrieving either recursively, or from an input
+ file. Thus you may safely type `wget -Q2m -i sites'--download
+ will be aborted when the quota is exceeded.
+
+ Setting quota to 0 or to `inf' unlimits the download quota.
+
+`--no-dns-cache'
+ Turn off caching of DNS lookups. Normally, Wget remembers the IP
+ addresses it looked up from DNS so it doesn't have to repeatedly
+ contact the DNS server for the same (typically small) set of hosts
+ it retrieves from. This cache exists in memory only; a new Wget
+ run will contact DNS again.
+
+ However, it has been reported that in some situations it is not
+ desirable to cache host names, even for the duration of a
+ short-running application like Wget. With this option Wget issues
+ a new DNS lookup (more precisely, a new call to `gethostbyname' or
+ `getaddrinfo') each time it makes a new connection. Please note
+ that this option will _not_ affect caching that might be performed
+ by the resolving library or by an external caching layer, such as
+ NSCD.
+
+ If you don't understand exactly what this option does, you probably
+ won't need it.
+
+`--restrict-file-names=MODE'
+ Change which characters found in remote URLs may show up in local
+ file names generated from those URLs. Characters that are
+ "restricted" by this option are escaped, i.e. replaced with `%HH',
+ where `HH' is the hexadecimal number that corresponds to the
+ restricted character.
+
+ By default, Wget escapes the characters that are not valid as part
+ of file names on your operating system, as well as control
+ characters that are typically unprintable. This option is useful
+ for changing these defaults, either because you are downloading to
+ a non-native partition, or because you want to disable escaping of
+ the control characters.
+
+ When mode is set to "unix", Wget escapes the character `/' and the
+ control characters in the ranges 0-31 and 128-159. This is the
+ default on Unix-like OS'es.
+
+ When mode is set to "windows", Wget escapes the characters `\',
+ `|', `/', `:', `?', `"', `*', `<', `>', and the control characters
+ in the ranges 0-31 and 128-159. In addition to this, Wget in
+ Windows mode uses `+' instead of `:' to separate host and port in
+ local file names, and uses `@' instead of `?' to separate the
+ query portion of the file name from the rest. Therefore, a URL
+ that would be saved as `www.xemacs.org:4300/search.pl?input=blah'
+ in Unix mode would be saved as
+ `www.xemacs.org+4300/search.pl@input=blah' in Windows mode. This
+ mode is the default on Windows.
+
+ If you append `,nocontrol' to the mode, as in `unix,nocontrol',
+ escaping of the control characters is also switched off. You can
+ use `--restrict-file-names=nocontrol' to turn off escaping of
+ control characters without affecting the choice of the OS to use
+ as file name restriction mode.
+
+`-4'
+`--inet4-only'
+`-6'
+`--inet6-only'
+ Force connecting to IPv4 or IPv6 addresses. With `--inet4-only'
+ or `-4', Wget will only connect to IPv4 hosts, ignoring AAAA
+ records in DNS, and refusing to connect to IPv6 addresses
+ specified in URLs. Conversely, with `--inet6-only' or `-6', Wget
+ will only connect to IPv6 hosts and ignore A records and IPv4
+ addresses.
+
+ Neither options should be needed normally. By default, an
+ IPv6-aware Wget will use the address family specified by the
+ host's DNS record. If the DNS responds with both IPv4 and IPv6
+ addresses, Wget will them in sequence until it finds one it can
+ connect to. (Also see `--prefer-family' option described below.)
+
+ These options can be used to deliberately force the use of IPv4 or
+ IPv6 address families on dual family systems, usually to aid
+ debugging or to deal with broken network configuration. Only one
+ of `--inet6-only' and `--inet4-only' may be specified at the same
+ time. Neither option is available in Wget compiled without IPv6
+ support.
+
+`--prefer-family=IPv4/IPv6/none'
+ When given a choice of several addresses, connect to the addresses
+ with specified address family first. IPv4 addresses are preferred
+ by default.
+
+ This avoids spurious errors and connect attempts when accessing
+ hosts that resolve to both IPv6 and IPv4 addresses from IPv4
+ networks. For example, `www.kame.net' resolves to
+ `2001:200:0:8002:203:47ff:fea5:3085' and to `203.178.141.194'.
+ When the preferred family is `IPv4', the IPv4 address is used
+ first; when the preferred family is `IPv6', the IPv6 address is
+ used first; if the specified value is `none', the address order
+ returned by DNS is used without change.
+
+ Unlike `-4' and `-6', this option doesn't inhibit access to any
+ address family, it only changes the _order_ in which the addresses
+ are accessed. Also note that the reordering performed by this
+ option is "stable"--it doesn't affect order of addresses of the
+ same family. That is, the relative order of all IPv4 addresses
+ and of all IPv6 addresses remains intact in all cases.
+
+`--retry-connrefused'
+ Consider "connection refused" a transient error and try again.
+ Normally Wget gives up on a URL when it is unable to connect to the
+ site because failure to connect is taken as a sign that the server
+ is not running at all and that retries would not help. This
+ option is for mirroring unreliable sites whose servers tend to
+ disappear for short periods of time.
+
+`--user=USER'
+`--password=PASSWORD'
+ Specify the username USER and password PASSWORD for both FTP and
+ HTTP file retrieval. These parameters can be overridden using the
+ `--ftp-user' and `--ftp-password' options for FTP connections and
+ the `--http-user' and `--http-password' options for HTTP
+ connections.

+
+2.6 Directory Options
+=====================
+
+`-nd'
+`--no-directories'
+ Do not create a hierarchy of directories when retrieving
+ recursively. With this option turned on, all files will get saved
+ to the current directory, without clobbering (if a name shows up
+ more than once, the filenames will get extensions `.n').
+
+`-x'
+`--force-directories'
+ The opposite of `-nd'--create a hierarchy of directories, even if
+ one would not have been created otherwise. E.g. `wget -x
+ http://fly.srk.fer.hr/robots.txt' will save the downloaded file to
+ `fly.srk.fer.hr/robots.txt'.
+
+`-nH'
+`--no-host-directories'
+ Disable generation of host-prefixed directories. By default,
+ invoking Wget with `-r http://fly.srk.fer.hr/' will create a
+ structure of directories beginning with `fly.srk.fer.hr/'. This
+ option disables such behavior.
+
+`--protocol-directories'
+ Use the protocol name as a directory component of local file
+ names. For example, with this option, `wget -r http://HOST' will
+ save to `http/HOST/...' rather than just to `HOST/...'.
+
+`--cut-dirs=NUMBER'
+ Ignore NUMBER directory components. This is useful for getting a
+ fine-grained control over the directory where recursive retrieval
+ will be saved.
+
+ Take, for example, the directory at
+ `ftp://ftp.xemacs.org/pub/xemacs/'. If you retrieve it with `-r',
+ it will be saved locally under `ftp.xemacs.org/pub/xemacs/'.
+ While the `-nH' option can remove the `ftp.xemacs.org/' part, you
+ are still stuck with `pub/xemacs'. This is where `--cut-dirs'
+ comes in handy; it makes Wget not "see" NUMBER remote directory
+ components. Here are several examples of how `--cut-dirs' option
+ works.
+
+ No options -> ftp.xemacs.org/pub/xemacs/
+ -nH -> pub/xemacs/
+ -nH --cut-dirs=1 -> xemacs/
+ -nH --cut-dirs=2 -> .
+
+ --cut-dirs=1 -> ftp.xemacs.org/xemacs/
+ ...
+
+ If you just want to get rid of the directory structure, this
+ option is similar to a combination of `-nd' and `-P'. However,
+ unlike `-nd', `--cut-dirs' does not lose with subdirectories--for
+ instance, with `-nH --cut-dirs=1', a `beta/' subdirectory will be
+ placed to `xemacs/beta', as one would expect.
+
+`-P PREFIX'
+`--directory-prefix=PREFIX'
+ Set directory prefix to PREFIX. The "directory prefix" is the
+ directory where all other files and subdirectories will be saved
+ to, i.e. the top of the retrieval tree. The default is `.' (the
+ current directory).
+
+

+
+2.7 HTTP Options
+================
+
+`-E'
+`--html-extension'
+ If a file of type `application/xhtml+xml' or `text/html' is
+ downloaded and the URL does not end with the regexp
+ `\.[Hh][Tt][Mm][Ll]?', this option will cause the suffix `.html'
+ to be appended to the local filename. This is useful, for
+ instance, when you're mirroring a remote site that uses `.asp'
+ pages, but you want the mirrored pages to be viewable on your
+ stock Apache server. Another good use for this is when you're
+ downloading CGI-generated materials. A URL like
+ `http://site.com/article.cgi?25' will be saved as
+ `article.cgi?25.html'.
+
+ Note that filenames changed in this way will be re-downloaded
+ every time you re-mirror a site, because Wget can't tell that the
+ local `X.html' file corresponds to remote URL `X' (since it
+ doesn't yet know that the URL produces output of type `text/html'
+ or `application/xhtml+xml'. To prevent this re-downloading, you
+ must use `-k' and `-K' so that the original version of the file
+ will be saved as `X.orig' (*note Recursive Retrieval Options::).
+
+`--http-user=USER'
+`--http-password=PASSWORD'
+ Specify the username USER and password PASSWORD on an HTTP server.
+ According to the type of the challenge, Wget will encode them
+ using either the `basic' (insecure) or the `digest' authentication
+ scheme.
+
+ Another way to specify username and password is in the URL itself
+ (*note URL Format::). Either method reveals your password to
+ anyone who bothers to run `ps'. To prevent the passwords from
+ being seen, store them in `.wgetrc' or `.netrc', and make sure to
+ protect those files from other users with `chmod'. If the
+ passwords are really important, do not leave them lying in those
+ files either--edit the files and delete them after Wget has
+ started the download.
+
+`--no-cache'
+ Disable server-side cache. In this case, Wget will send the remote
+ server an appropriate directive (`Pragma: no-cache') to get the
+ file from the remote service, rather than returning the cached
+ version. This is especially useful for retrieving and flushing
+ out-of-date documents on proxy servers.
+
+ Caching is allowed by default.
+
+`--no-cookies'
+ Disable the use of cookies. Cookies are a mechanism for
+ maintaining server-side state. The server sends the client a
+ cookie using the `Set-Cookie' header, and the client responds with
+ the same cookie upon further requests. Since cookies allow the
+ server owners to keep track of visitors and for sites to exchange
+ this information, some consider them a breach of privacy. The
+ default is to use cookies; however, _storing_ cookies is not on by
+ default.
+
+`--load-cookies FILE'
+ Load cookies from FILE before the first HTTP retrieval. FILE is a
+ textual file in the format originally used by Netscape's
+ `cookies.txt' file.
+
+ You will typically use this option when mirroring sites that
+ require that you be logged in to access some or all of their
+ content. The login process typically works by the web server
+ issuing an HTTP cookie upon receiving and verifying your
+ credentials. The cookie is then resent by the browser when
+ accessing that part of the site, and so proves your identity.
+
+ Mirroring such a site requires Wget to send the same cookies your
+ browser sends when communicating with the site. This is achieved
+ by `--load-cookies'--simply point Wget to the location of the
+ `cookies.txt' file, and it will send the same cookies your browser
+ would send in the same situation. Different browsers keep textual
+ cookie files in different locations:
+
+ Netscape 4.x.
+ The cookies are in `~/.netscape/cookies.txt'.
+
+ Mozilla and Netscape 6.x.
+ Mozilla's cookie file is also named `cookies.txt', located
+ somewhere under `~/.mozilla', in the directory of your
+ profile. The full path usually ends up looking somewhat like
+ `~/.mozilla/default/SOME-WEIRD-STRING/cookies.txt'.
+
+ Internet Explorer.
+ You can produce a cookie file Wget can use by using the File
+ menu, Import and Export, Export Cookies. This has been
+ tested with Internet Explorer 5; it is not guaranteed to work
+ with earlier versions.
+
+ Other browsers.
+ If you are using a different browser to create your cookies,
+ `--load-cookies' will only work if you can locate or produce a
+ cookie file in the Netscape format that Wget expects.
+
+ If you cannot use `--load-cookies', there might still be an
+ alternative. If your browser supports a "cookie manager", you can
+ use it to view the cookies used when accessing the site you're
+ mirroring. Write down the name and value of the cookie, and
+ manually instruct Wget to send those cookies, bypassing the
+ "official" cookie support:
+
+ wget --no-cookies --header "Cookie: NAME=VALUE"
+
+`--save-cookies FILE'
+ Save cookies to FILE before exiting. This will not save cookies
+ that have expired or that have no expiry time (so-called "session
+ cookies"), but also see `--keep-session-cookies'.
+
+`--keep-session-cookies'
+ When specified, causes `--save-cookies' to also save session
+ cookies. Session cookies are normally not saved because they are
+ meant to be kept in memory and forgotten when you exit the browser.
+ Saving them is useful on sites that require you to log in or to
+ visit the home page before you can access some pages. With this
+ option, multiple Wget runs are considered a single browser session
+ as far as the site is concerned.
+
+ Since the cookie file format does not normally carry session
+ cookies, Wget marks them with an expiry timestamp of 0. Wget's
+ `--load-cookies' recognizes those as session cookies, but it might
+ confuse other browsers. Also note that cookies so loaded will be
+ treated as other session cookies, which means that if you want
+ `--save-cookies' to preserve them again, you must use
+ `--keep-session-cookies' again.
+
+`--ignore-length'
+ Unfortunately, some HTTP servers (CGI programs, to be more
+ precise) send out bogus `Content-Length' headers, which makes Wget
+ go wild, as it thinks not all the document was retrieved. You can
+ spot this syndrome if Wget retries getting the same document again
+ and again, each time claiming that the (otherwise normal)
+ connection has closed on the very same byte.
+
+ With this option, Wget will ignore the `Content-Length' header--as
+ if it never existed.
+
+`--header=HEADER-LINE'
+ Send HEADER-LINE along with the rest of the headers in each HTTP
+ request. The supplied header is sent as-is, which means it must
+ contain name and value separated by colon, and must not contain
+ newlines.
+
+ You may define more than one additional header by specifying
+ `--header' more than once.
+
+ wget --header='Accept-Charset: iso-8859-2' \
+ --header='Accept-Language: hr' \
+ http://fly.srk.fer.hr/
+
+ Specification of an empty string as the header value will clear all
+ previous user-defined headers.
+
+ As of Wget 1.10, this option can be used to override headers
+ otherwise generated automatically. This example instructs Wget to
+ connect to localhost, but to specify `foo.bar' in the `Host'
+ header:
+
+ wget --header="Host: foo.bar" http://localhost/
+
+ In versions of Wget prior to 1.10 such use of `--header' caused
+ sending of duplicate headers.
+
+`--proxy-user=USER'
+`--proxy-password=PASSWORD'
+ Specify the username USER and password PASSWORD for authentication
+ on a proxy server. Wget will encode them using the `basic'
+ authentication scheme.
+
+ Security considerations similar to those with `--http-password'
+ pertain here as well.
+
+`--referer=URL'
+ Include `Referer: URL' header in HTTP request. Useful for
+ retrieving documents with server-side processing that assume they
+ are always being retrieved by interactive web browsers and only
+ come out properly when Referer is set to one of the pages that
+ point to them.
+
+`--save-headers'
+ Save the headers sent by the HTTP server to the file, preceding the
+ actual contents, with an empty line as the separator.
+
+`-U AGENT-STRING'
+`--user-agent=AGENT-STRING'
+ Identify as AGENT-STRING to the HTTP server.
+
+ The HTTP protocol allows the clients to identify themselves using a
+ `User-Agent' header field. This enables distinguishing the WWW
+ software, usually for statistical purposes or for tracing of
+ protocol violations. Wget normally identifies as `Wget/VERSION',
+ VERSION being the current version number of Wget.
+
+ However, some sites have been known to impose the policy of
+ tailoring the output according to the `User-Agent'-supplied
+ information. While this is not such a bad idea in theory, it has
+ been abused by servers denying information to clients other than
+ (historically) Netscape or, more frequently, Microsoft Internet
+ Explorer. This option allows you to change the `User-Agent' line
+ issued by Wget. Use of this option is discouraged, unless you
+ really know what you are doing.
+
+ Specifying empty user agent with `--user-agent=""' instructs Wget
+ not to send the `User-Agent' header in HTTP requests.
+
+`--post-data=STRING'
+`--post-file=FILE'
+ Use POST as the method for all HTTP requests and send the
+ specified data in the request body. `--post-data' sends STRING as
+ data, whereas `--post-file' sends the contents of FILE. Other than
+ that, they work in exactly the same way.
+
+ Please be aware that Wget needs to know the size of the POST data
+ in advance. Therefore the argument to `--post-file' must be a
+ regular file; specifying a FIFO or something like `/dev/stdin'
+ won't work. It's not quite clear how to work around this
+ limitation inherent in HTTP/1.0. Although HTTP/1.1 introduces
+ "chunked" transfer that doesn't require knowing the request length
+ in advance, a client can't use chunked unless it knows it's
+ talking to an HTTP/1.1 server. And it can't know that until it
+ receives a response, which in turn requires the request to have
+ been completed - a chicken-and-egg problem.
+
+ Note: if Wget is redirected after the POST request is completed, it
+ will not send the POST data to the redirected URL. This is because
+ URLs that process POST often respond with a redirection to a
+ regular page, which does not desire or accept POST. It is not
+ completely clear that this behavior is optimal; if it doesn't work
+ out, it might be changed in the future.
+
+ This example shows how to log to a server using POST and then
+ proceed to download the desired pages, presumably only accessible
+ to authorized users:
+
+ # Log in to the server. This can be done only once.
+ wget --save-cookies cookies.txt \
+ --post-data 'user=foo&password=bar' \
+ http://server.com/auth.php
+
+ # Now grab the page or pages we care about.
+ wget --load-cookies cookies.txt \
+ -p http://server.com/interesting/article.php
+
+ If the server is using session cookies to track user
+ authentication, the above will not work because `--save-cookies'
+ will not save them (and neither will browsers) and the
+ `cookies.txt' file will be empty. In that case use
+ `--keep-session-cookies' along with `--save-cookies' to force
+ saving of session cookies.

+
+2.8 HTTPS (SSL/TLS) Options
+===========================
+
+To support encrypted HTTP (HTTPS) downloads, Wget must be compiled with
+an external SSL library, currently OpenSSL. If Wget is compiled
+without SSL support, none of these options are available.
+
+`--secure-protocol=PROTOCOL'
+ Choose the secure protocol to be used. Legal values are `auto',
+ `SSLv2', `SSLv3', and `TLSv1'. If `auto' is used, the SSL library
+ is given the liberty of choosing the appropriate protocol
+ automatically, which is achieved by sending an SSLv2 greeting and
+ announcing support for SSLv3 and TLSv1. This is the default.
+
+ Specifying `SSLv2', `SSLv3', or `TLSv1' forces the use of the
+ corresponding protocol. This is useful when talking to old and
+ buggy SSL server implementations that make it hard for OpenSSL to
+ choose the correct protocol version. Fortunately, such servers are
+ quite rare.
+
+`--no-check-certificate'
+ Don't check the server certificate against the available
+ certificate authorities. Also don't require the URL host name to
+ match the common name presented by the certificate.
+
+ As of Wget 1.10, the default is to verify the server's certificate
+ against the recognized certificate authorities, breaking the SSL
+ handshake and aborting the download if the verification fails.
+ Although this provides more secure downloads, it does break
+ interoperability with some sites that worked with previous Wget
+ versions, particularly those using self-signed, expired, or
+ otherwise invalid certificates. This option forces an "insecure"
+ mode of operation that turns the certificate verification errors
+ into warnings and allows you to proceed.
+
+ If you encounter "certificate verification" errors or ones saying
+ that "common name doesn't match requested host name", you can use
+ this option to bypass the verification and proceed with the
+ download. _Only use this option if you are otherwise convinced of
+ the site's authenticity, or if you really don't care about the
+ validity of its certificate._ It is almost always a bad idea not
+ to check the certificates when transmitting confidential or
+ important data.
+
+`--certificate=FILE'
+ Use the client certificate stored in FILE. This is needed for
+ servers that are configured to require certificates from the
+ clients that connect to them. Normally a certificate is not
+ required and this switch is optional.
+
+`--certificate-type=TYPE'
+ Specify the type of the client certificate. Legal values are
+ `PEM' (assumed by default) and `DER', also known as `ASN1'.
+
+`--private-key=FILE'
+ Read the private key from FILE. This allows you to provide the
+ private key in a file separate from the certificate.
+
+`--private-key-type=TYPE'
+ Specify the type of the private key. Accepted values are `PEM'
+ (the default) and `DER'.
+
+`--ca-certificate=FILE'
+ Use FILE as the file with the bundle of certificate authorities
+ ("CA") to verify the peers. The certificates must be in PEM
+ format.
+
+ Without this option Wget looks for CA certificates at the
+ system-specified locations, chosen at OpenSSL installation time.
+
+`--ca-directory=DIRECTORY'
+ Specifies directory containing CA certificates in PEM format. Each
+ file contains one CA certificate, and the file name is based on a
+ hash value derived from the certificate. This is achieved by
+ processing a certificate directory with the `c_rehash' utility
+ supplied with OpenSSL. Using `--ca-directory' is more efficient
+ than `--ca-certificate' when many certificates are installed
+ because it allows Wget to fetch certificates on demand.
+
+ Without this option Wget looks for CA certificates at the
+ system-specified locations, chosen at OpenSSL installation time.
+
+`--random-file=FILE'
+ Use FILE as the source of random data for seeding the
+ pseudo-random number generator on systems without `/dev/random'.
+
+ On such systems the SSL library needs an external source of
+ randomness to initialize. Randomness may be provided by EGD (see
+ `--egd-file' below) or read from an external source specified by
+ the user. If this option is not specified, Wget looks for random
+ data in `$RANDFILE' or, if that is unset, in `$HOME/.rnd'. If
+ none of those are available, it is likely that SSL encryption will
+ not be usable.
+
+ If you're getting the "Could not seed OpenSSL PRNG; disabling SSL."
+ error, you should provide random data using some of the methods
+ described above.
+
+`--egd-file=FILE'
+ Use FILE as the EGD socket. EGD stands for "Entropy Gathering
+ Daemon", a user-space program that collects data from various
+ unpredictable system sources and makes it available to other
+ programs that might need it. Encryption software, such as the SSL
+ library, needs sources of non-repeating randomness to seed the
+ random number generator used to produce cryptographically strong
+ keys.
+
+ OpenSSL allows the user to specify his own source of entropy using
+ the `RAND_FILE' environment variable. If this variable is unset,
+ or if the specified file does not produce enough randomness,
+ OpenSSL will read random data from EGD socket specified using this
+ option.
+
+ If this option is not specified (and the equivalent startup
+ command is not used), EGD is never contacted. EGD is not needed
+ on modern Unix systems that support `/dev/random'.

+2.9 FTP Options
+===============
+
+`--ftp-user=USER'
+`--ftp-password=PASSWORD'
+ Specify the username USER and password PASSWORD on an FTP server.
+ Without this, or the corresponding startup option, the password
+ defaults to `-wget@', normally used for anonymous FTP.
+
+ Another way to specify username and password is in the URL itself
+ (*note URL Format::). Either method reveals your password to
+ anyone who bothers to run `ps'. To prevent the passwords from
+ being seen, store them in `.wgetrc' or `.netrc', and make sure to
+ protect those files from other users with `chmod'. If the
+ passwords are really important, do not leave them lying in those
+ files either--edit the files and delete them after Wget has
+ started the download.
+
+`--no-remove-listing'
+ Don't remove the temporary `.listing' files generated by FTP
+ retrievals. Normally, these files contain the raw directory
+ listings received from FTP servers. Not removing them can be
+ useful for debugging purposes, or when you want to be able to
+ easily check on the contents of remote server directories (e.g. to
+ verify that a mirror you're running is complete).
+
+ Note that even though Wget writes to a known filename for this
+ file, this is not a security hole in the scenario of a user making
+ `.listing' a symbolic link to `/etc/passwd' or something and
+ asking `root' to run Wget in his or her directory. Depending on
+ the options used, either Wget will refuse to write to `.listing',
+ making the globbing/recursion/time-stamping operation fail, or the
+ symbolic link will be deleted and replaced with the actual
+ `.listing' file, or the listing will be written to a
+ `.listing.NUMBER' file.
+
+ Even though this situation isn't a problem, though, `root' should
+ never run Wget in a non-trusted user's directory. A user could do
+ something as simple as linking `index.html' to `/etc/passwd' and
+ asking `root' to run Wget with `-N' or `-r' so the file will be
+ overwritten.
+
+`--no-glob'
+ Turn off FTP globbing. Globbing refers to the use of shell-like
+ special characters ("wildcards"), like `*', `?', `[' and `]' to
+ retrieve more than one file from the same directory at once, like:
+
+ wget ftp://gnjilux.srk.fer.hr/*.msg
+
+ By default, globbing will be turned on if the URL contains a
+ globbing character. This option may be used to turn globbing on
+ or off permanently.
+
+ You may have to quote the URL to protect it from being expanded by
+ your shell. Globbing makes Wget look for a directory listing,
+ which is system-specific. This is why it currently works only
+ with Unix FTP servers (and the ones emulating Unix `ls' output).
+
+`--no-passive-ftp'
+ Disable the use of the "passive" FTP transfer mode. Passive FTP
+ mandates that the client connect to the server to establish the
+ data connection rather than the other way around.
+
+ If the machine is connected to the Internet directly, both passive
+ and active FTP should work equally well. Behind most firewall and
+ NAT configurations passive FTP has a better chance of working.
+ However, in some rare firewall configurations, active FTP actually
+ works when passive FTP doesn't. If you suspect this to be the
+ case, use this option, or set `passive_ftp=off' in your init file.
+
+`--retr-symlinks'
+ Usually, when retrieving FTP directories recursively and a symbolic
+ link is encountered, the linked-to file is not downloaded.
+ Instead, a matching symbolic link is created on the local
+ filesystem. The pointed-to file will not be downloaded unless
+ this recursive retrieval would have encountered it separately and
+ downloaded it anyway.
+
+ When `--retr-symlinks' is specified, however, symbolic links are
+ traversed and the pointed-to files are retrieved. At this time,
+ this option does not cause Wget to traverse symlinks to
+ directories and recurse through them, but in the future it should
+ be enhanced to do this.
+
+ Note that when retrieving a file (not a directory) because it was
+ specified on the command-line, rather than because it was recursed
+ to, this option has no effect. Symbolic links are always
+ traversed in this case.
+
+`--no-http-keep-alive'
+ Turn off the "keep-alive" feature for HTTP downloads. Normally,
+ Wget asks the server to keep the connection open so that, when you
+ download more than one document from the same server, they get
+ transferred over the same TCP connection. This saves time and at
+ the same time reduces the load on the server.
+
+ This option is useful when, for some reason, persistent
+ (keep-alive) connections don't work for you, for example due to a
+ server bug or due to the inability of server-side scripts to cope
+ with the connections.

+2.10 Recursive Retrieval Options
+================================
+
+`-r'
+`--recursive'
+ Turn on recursive retrieving. *Note Recursive Download::, for more
+ details.
+
+`-l DEPTH'
+`--level=DEPTH'
+ Specify recursion maximum depth level DEPTH (*note Recursive
+ Download::). The default maximum depth is 5.
+
+`--delete-after'
+ This option tells Wget to delete every single file it downloads,
+ _after_ having done so. It is useful for pre-fetching popular
+ pages through a proxy, e.g.:
+
+ wget -r -nd --delete-after http://whatever.com/~popular/page/
+
+ The `-r' option is to retrieve recursively, and `-nd' to not
+ create directories.
+
+ Note that `--delete-after' deletes files on the local machine. It
+ does not issue the `DELE' command to remote FTP sites, for
+ instance. Also note that when `--delete-after' is specified,
+ `--convert-links' is ignored, so `.orig' files are simply not
+ created in the first place.
+
+`-k'
+`--convert-links'
+ After the download is complete, convert the links in the document
+ to make them suitable for local viewing. This affects not only
+ the visible hyperlinks, but any part of the document that links to
+ external content, such as embedded images, links to style sheets,
+ hyperlinks to non-HTML content, etc.
+
+ Each link will be changed in one of the two ways:
+
+ * The links to files that have been downloaded by Wget will be
+ changed to refer to the file they point to as a relative link.
+
+ Example: if the downloaded file `/foo/doc.html' links to
+ `/bar/img.gif', also downloaded, then the link in `doc.html'
+ will be modified to point to `../bar/img.gif'. This kind of
+ transformation works reliably for arbitrary combinations of
+ directories.
+
+ * The links to files that have not been downloaded by Wget will
+ be changed to include host name and absolute path of the
+ location they point to.
+
+ Example: if the downloaded file `/foo/doc.html' links to
+ `/bar/img.gif' (or to `../bar/img.gif'), then the link in
+ `doc.html' will be modified to point to
+ `http://HOSTNAME/bar/img.gif'.
+
+ Because of this, local browsing works reliably: if a linked file
+ was downloaded, the link will refer to its local name; if it was
+ not downloaded, the link will refer to its full Internet address
+ rather than presenting a broken link. The fact that the former
+ links are converted to relative links ensures that you can move
+ the downloaded hierarchy to another directory.
+
+ Note that only at the end of the download can Wget know which
+ links have been downloaded. Because of that, the work done by
+ `-k' will be performed at the end of all the downloads.
+
+`-K'
+`--backup-converted'
+ When converting a file, back up the original version with a `.orig'
+ suffix. Affects the behavior of `-N' (*note HTTP Time-Stamping
+ Internals::).
+
+`-m'
+`--mirror'
+ Turn on options suitable for mirroring. This option turns on
+ recursion and time-stamping, sets infinite recursion depth and
+ keeps FTP directory listings. It is currently equivalent to `-r
+ -N -l inf --no-remove-listing'.
+
+`-p'
+`--page-requisites'
+ This option causes Wget to download all the files that are
+ necessary to properly display a given HTML page. This includes
+ such things as inlined images, sounds, and referenced stylesheets.
+
+ Ordinarily, when downloading a single HTML page, any requisite
+ documents that may be needed to display it properly are not
+ downloaded. Using `-r' together with `-l' can help, but since
+ Wget does not ordinarily distinguish between external and inlined
+ documents, one is generally left with "leaf documents" that are
+ missing their requisites.
+
+ For instance, say document `1.html' contains an `<IMG>' tag
+ referencing `1.gif' and an `<A>' tag pointing to external document
+ `2.html'. Say that `2.html' is similar but that its image is
+ `2.gif' and it links to `3.html'. Say this continues up to some
+ arbitrarily high number.
+
+ If one executes the command:
+
+ wget -r -l 2 http://SITE/1.html
+
+ then `1.html', `1.gif', `2.html', `2.gif', and `3.html' will be
+ downloaded. As you can see, `3.html' is without its requisite
+ `3.gif' because Wget is simply counting the number of hops (up to
+ 2) away from `1.html' in order to determine where to stop the
+ recursion. However, with this command:
+
+ wget -r -l 2 -p http://SITE/1.html
+
+ all the above files _and_ `3.html''s requisite `3.gif' will be
+ downloaded. Similarly,
+
+ wget -r -l 1 -p http://SITE/1.html
+
+ will cause `1.html', `1.gif', `2.html', and `2.gif' to be
+ downloaded. One might think that:
+
+ wget -r -l 0 -p http://SITE/1.html
+
+ would download just `1.html' and `1.gif', but unfortunately this
+ is not the case, because `-l 0' is equivalent to `-l inf'--that
+ is, infinite recursion. To download a single HTML page (or a
+ handful of them, all specified on the command-line or in a `-i'
+ URL input file) and its (or their) requisites, simply leave off
+ `-r' and `-l':
+
+ wget -p http://SITE/1.html
+
+ Note that Wget will behave as if `-r' had been specified, but only
+ that single page and its requisites will be downloaded. Links
+ from that page to external documents will not be followed.
+ Actually, to download a single page and all its requisites (even
+ if they exist on separate websites), and make sure the lot
+ displays properly locally, this author likes to use a few options
+ in addition to `-p':
+
+ wget -E -H -k -K -p http://SITE/DOCUMENT
+
+ To finish off this topic, it's worth knowing that Wget's idea of an
+ external document link is any URL specified in an `<A>' tag, an
+ `<AREA>' tag, or a `<LINK>' tag other than `<LINK
+ REL="stylesheet">'.
+
+`--strict-comments'
+ Turn on strict parsing of HTML comments. The default is to
+ terminate comments at the first occurrence of `-->'.
+
+ According to specifications, HTML comments are expressed as SGML
+ "declarations". Declaration is special markup that begins with
+ `<!' and ends with `>', such as `<!DOCTYPE ...>', that may contain
+ comments between a pair of `--' delimiters. HTML comments are
+ "empty declarations", SGML declarations without any non-comment
+ text. Therefore, `<!--foo-->' is a valid comment, and so is
+ `<!--one-- --two-->', but `<!--1--2-->' is not.
+
+ On the other hand, most HTML writers don't perceive comments as
+ anything other than text delimited with `<!--' and `-->', which is
+ not quite the same. For example, something like `<!------------>'
+ works as a valid comment as long as the number of dashes is a
+ multiple of four (!). If not, the comment technically lasts until
+ the next `--', which may be at the other end of the document.
+ Because of this, many popular browsers completely ignore the
+ specification and implement what users have come to expect:
+ comments delimited with `<!--' and `-->'.
+
+ Until version 1.9, Wget interpreted comments strictly, which
+ resulted in missing links in many web pages that displayed fine in
+ browsers, but had the misfortune of containing non-compliant
+ comments. Beginning with version 1.9, Wget has joined the ranks
+ of clients that implements "naive" comments, terminating each
+ comment at the first occurrence of `-->'.
+
+ If, for whatever reason, you want strict comment parsing, use this
+ option to turn it on.

+
+2.11 Recursive Accept/Reject Options
+====================================
+
+`-A ACCLIST --accept ACCLIST'
+`-R REJLIST --reject REJLIST'
+ Specify comma-separated lists of file name suffixes or patterns to
+ accept or reject (*note Types of Files:: for more details).
+
+`-D DOMAIN-LIST'
+`--domains=DOMAIN-LIST'
+ Set domains to be followed. DOMAIN-LIST is a comma-separated list
+ of domains. Note that it does _not_ turn on `-H'.
+
+`--exclude-domains DOMAIN-LIST'
+ Specify the domains that are _not_ to be followed. (*note
+ Spanning Hosts::).
+
+`--follow-ftp'
+ Follow FTP links from HTML documents. Without this option, Wget
+ will ignore all the FTP links.
+
+`--follow-tags=LIST'
+ Wget has an internal table of HTML tag / attribute pairs that it
+ considers when looking for linked documents during a recursive
+ retrieval. If a user wants only a subset of those tags to be
+ considered, however, he or she should be specify such tags in a
+ comma-separated LIST with this option.
+
+`--ignore-tags=LIST'
+ This is the opposite of the `--follow-tags' option. To skip
+ certain HTML tags when recursively looking for documents to
+ download, specify them in a comma-separated LIST.
+
+ In the past, this option was the best bet for downloading a single
+ page and its requisites, using a command-line like:
+
+ wget --ignore-tags=a,area -H -k -K -r http://SITE/DOCUMENT
+
+ However, the author of this option came across a page with tags
+ like `<LINK REL="home" HREF="/">' and came to the realization that
+ specifying tags to ignore was not enough. One can't just tell
+ Wget to ignore `<LINK>', because then stylesheets will not be
+ downloaded. Now the best bet for downloading a single page and
+ its requisites is the dedicated `--page-requisites' option.
+
+`-H'
+`--span-hosts'
+ Enable spanning across hosts when doing recursive retrieving
+ (*note Spanning Hosts::).
+
+`-L'
+`--relative'
+ Follow relative links only. Useful for retrieving a specific home
+ page without any distractions, not even those from the same hosts
+ (*note Relative Links::).
+
+`-I LIST'
+`--include-directories=LIST'
+ Specify a comma-separated list of directories you wish to follow
+ when downloading (*note Directory-Based Limits:: for more
+ details.) Elements of LIST may contain wildcards.
+
+`-X LIST'
+`--exclude-directories=LIST'
+ Specify a comma-separated list of directories you wish to exclude
+ from download (*note Directory-Based Limits:: for more details.)
+ Elements of LIST may contain wildcards.
+
+`-np'
+
+`--no-parent'
+ Do not ever ascend to the parent directory when retrieving
+ recursively. This is a useful option, since it guarantees that
+ only the files _below_ a certain hierarchy will be downloaded.
+ *Note Directory-Based Limits::, for more details.

+
+3 Recursive Download
+********************
+
+GNU Wget is capable of traversing parts of the Web (or a single HTTP or
+FTP server), following links and directory structure. We refer to this
+as to "recursive retrieval", or "recursion".
+
+ With HTTP URLs, Wget retrieves and parses the HTML from the given
+URL, documents, retrieving the files the HTML document was referring
+to, through markup like `href', or `src'. If the freshly downloaded
+file is also of type `text/html' or `application/xhtml+xml', it will be
+parsed and followed further.
+
+ Recursive retrieval of HTTP and HTML content is "breadth-first".
+This means that Wget first downloads the requested HTML document, then
+the documents linked from that document, then the documents linked by
+them, and so on. In other words, Wget first downloads the documents at
+depth 1, then those at depth 2, and so on until the specified maximum
+depth.
+
+ The maximum "depth" to which the retrieval may descend is specified
+with the `-l' option. The default maximum depth is five layers.
+
+ When retrieving an FTP URL recursively, Wget will retrieve all the
+data from the given directory tree (including the subdirectories up to
+the specified depth) on the remote server, creating its mirror image
+locally. FTP retrieval is also limited by the `depth' parameter.
+Unlike HTTP recursion, FTP recursion is performed depth-first.
+
+ By default, Wget will create a local directory tree, corresponding to
+the one found on the remote server.
+
+ Recursive retrieving can find a number of applications, the most
+important of which is mirroring. It is also useful for WWW
+presentations, and any other opportunities where slow network
+connections should be bypassed by storing the files locally.
+
+ You should be warned that recursive downloads can overload the remote
+servers. Because of that, many administrators frown upon them and may
+ban access from your site if they detect very fast downloads of big
+amounts of content. When downloading from Internet servers, consider
+using the `-w' option to introduce a delay between accesses to the
+server. The download will take a while longer, but the server
+administrator will not be alarmed by your rudeness.
+
+ Of course, recursive download may cause problems on your machine. If
+left to run unchecked, it can easily fill up the disk. If downloading
+from local network, it can also take bandwidth on the system, as well as
+consume memory and CPU.
+
+ Try to specify the criteria that match the kind of download you are
+trying to achieve. If you want to download only one page, use
+`--page-requisites' without any additional recursion. If you want to
+download things under one directory, use `-np' to avoid downloading
+things from other directories. If you want to download all the files
+from one directory, use `-l 1' to make sure the recursion depth never
+exceeds one. *Note Following Links::, for more information about this.
+
+ Recursive retrieval should be used with care. Don't say you were not
+warned.

+4 Following Links
+*****************
+
+When retrieving recursively, one does not wish to retrieve loads of
+unnecessary data. Most of the time the users bear in mind exactly what
+they want to download, and want Wget to follow only specific links.
+
+ For example, if you wish to download the music archive from
+`fly.srk.fer.hr', you will not want to download all the home pages that
+happen to be referenced by an obscure part of the archive.
+
+ Wget possesses several mechanisms that allows you to fine-tune which
+links it will follow.
+
+* Menu:
+
+* Spanning Hosts:: (Un)limiting retrieval based on host name.
+* Types of Files:: Getting only certain files.
+* Directory-Based Limits:: Getting only certain directories.
+* Relative Links:: Follow relative links only.
+* FTP Links:: Following FTP links.
+
+
+File: wget.info, Node: Spanning Hosts, Next: Types of Files, Up: Following Links
+
+4.1 Spanning Hosts
+==================
+
+Wget's recursive retrieval normally refuses to visit hosts different
+than the one you specified on the command line. This is a reasonable
+default; without it, every retrieval would have the potential to turn
+your Wget into a small version of google.
+
+ However, visiting different hosts, or "host spanning," is sometimes
+a useful option. Maybe the images are served from a different server.
+Maybe you're mirroring a site that consists of pages interlinked between
+three servers. Maybe the server has two equivalent names, and the HTML
+pages refer to both interchangeably.
+
+Span to any host--`-H'
+ The `-H' option turns on host spanning, thus allowing Wget's
+ recursive run to visit any host referenced by a link. Unless
+ sufficient recursion-limiting criteria are applied depth, these
+ foreign hosts will typically link to yet more hosts, and so on
+ until Wget ends up sucking up much more data than you have
+ intended.
+
+Limit spanning to certain domains--`-D'
+ The `-D' option allows you to specify the domains that will be
+ followed, thus limiting the recursion only to the hosts that
+ belong to these domains. Obviously, this makes sense only in
+ conjunction with `-H'. A typical example would be downloading the
+ contents of `www.server.com', but allowing downloads from
+ `images.server.com', etc.:
+
+ wget -rH -Dserver.com http://www.server.com/
+
+ You can specify more than one address by separating them with a
+ comma, e.g. `-Ddomain1.com,domain2.com'.
+
+Keep download off certain domains--`--exclude-domains'
+ If there are domains you want to exclude specifically, you can do
+ it with `--exclude-domains', which accepts the same type of
+ arguments of `-D', but will _exclude_ all the listed domains. For
+ example, if you want to download all the hosts from `foo.edu'
+ domain, with the exception of `sunsite.foo.edu', you can do it like
+ this:
+
+ wget -rH -Dfoo.edu --exclude-domains sunsite.foo.edu \
+ http://www.foo.edu/

+
+4.2 Types of Files
+==================
+
+When downloading material from the web, you will often want to restrict
+the retrieval to only certain file types. For example, if you are
+interested in downloading GIFs, you will not be overjoyed to get loads
+of PostScript documents, and vice versa.
+
+ Wget offers two options to deal with this problem. Each option
+description lists a short name, a long name, and the equivalent command
+in `.wgetrc'.
+
+`-A ACCLIST'
+`--accept ACCLIST'
+`accept = ACCLIST'
+ The argument to `--accept' option is a list of file suffixes or
+ patterns that Wget will download during recursive retrieval. A
+ suffix is the ending part of a file, and consists of "normal"
+ letters, e.g. `gif' or `.jpg'. A matching pattern contains
+ shell-like wildcards, e.g. `books*' or `zelazny*196[0-9]*'.
+
+ So, specifying `wget -A gif,jpg' will make Wget download only the
+ files ending with `gif' or `jpg', i.e. GIFs and JPEGs. On the
+ other hand, `wget -A "zelazny*196[0-9]*"' will download only files
+ beginning with `zelazny' and containing numbers from 1960 to 1969
+ anywhere within. Look up the manual of your shell for a
+ description of how pattern matching works.
+
+ Of course, any number of suffixes and patterns can be combined
+ into a comma-separated list, and given as an argument to `-A'.
+
+`-R REJLIST'
+`--reject REJLIST'
+`reject = REJLIST'
+ The `--reject' option works the same way as `--accept', only its
+ logic is the reverse; Wget will download all files _except_ the
+ ones matching the suffixes (or patterns) in the list.
+
+ So, if you want to download a whole page except for the cumbersome
+ MPEGs and .AU files, you can use `wget -R mpg,mpeg,au'.
+ Analogously, to download all files except the ones beginning with
+ `bjork', use `wget -R "bjork*"'. The quotes are to prevent
+ expansion by the shell.
+
+ The `-A' and `-R' options may be combined to achieve even better
+fine-tuning of which files to retrieve. E.g. `wget -A "*zelazny*" -R
+.ps' will download all the files having `zelazny' as a part of their
+name, but _not_ the PostScript files.
+
+ Note that these two options do not affect the downloading of HTML
+files; Wget must load all the HTMLs to know where to go at
+all--recursive retrieval would make no sense otherwise.
+
+
+File: wget.info, Node: Directory-Based Limits, Next: Relative Links, Prev: Types of Files, Up: Following Links
+
+4.3 Directory-Based Limits
+==========================
+
+Regardless of other link-following facilities, it is often useful to
+place the restriction of what files to retrieve based on the directories
+those files are placed in. There can be many reasons for this--the
+home pages may be organized in a reasonable directory structure; or some
+directories may contain useless information, e.g. `/cgi-bin' or `/dev'
+directories.
+
+ Wget offers three different options to deal with this requirement.
+Each option description lists a short name, a long name, and the
+equivalent command in `.wgetrc'.
+
+`-I LIST'
+`--include LIST'
+`include_directories = LIST'
+ `-I' option accepts a comma-separated list of directories included
+ in the retrieval. Any other directories will simply be ignored.
+ The directories are absolute paths.
+
+ So, if you wish to download from `http://host/people/bozo/'
+ following only links to bozo's colleagues in the `/people'
+ directory and the bogus scripts in `/cgi-bin', you can specify:
+
+ wget -I /people,/cgi-bin http://host/people/bozo/
+
+`-X LIST'
+`--exclude LIST'
+`exclude_directories = LIST'
+ `-X' option is exactly the reverse of `-I'--this is a list of
+ directories _excluded_ from the download. E.g. if you do not want
+ Wget to download things from `/cgi-bin' directory, specify `-X
+ /cgi-bin' on the command line.
+
+ The same as with `-A'/`-R', these two options can be combined to
+ get a better fine-tuning of downloading subdirectories. E.g. if
+ you want to load all the files from `/pub' hierarchy except for
+ `/pub/worthless', specify `-I/pub -X/pub/worthless'.
+
+`-np'
+`--no-parent'
+`no_parent = on'
+ The simplest, and often very useful way of limiting directories is
+ disallowing retrieval of the links that refer to the hierarchy
+ "above" than the beginning directory, i.e. disallowing ascent to
+ the parent directory/directories.
+
+ The `--no-parent' option (short `-np') is useful in this case.
+ Using it guarantees that you will never leave the existing
+ hierarchy. Supposing you issue Wget with:
+
+ wget -r --no-parent http://somehost/~luzer/my-archive/
+
+ You may rest assured that none of the references to
+ `/~his-girls-homepage/' or `/~luzer/all-my-mpegs/' will be
+ followed. Only the archive you are interested in will be
+ downloaded. Essentially, `--no-parent' is similar to
+ `-I/~luzer/my-archive', only it handles redirections in a more
+ intelligent fashion.
+
+
+File: wget.info, Node: Relative Links, Next: FTP Links, Prev: Directory-Based Limits, Up: Following Links
+
+4.4 Relative Links
+==================
+
+When `-L' is turned on, only the relative links are ever followed.
+Relative links are here defined those that do not refer to the web
+server root. For example, these links are relative:
+
+ <a href="foo.gif">
+ <a href="foo/bar.gif">
+ <a href="../foo/bar.gif">
+
+ These links are not relative:
+
+ <a href="/foo.gif">
+ <a href="/foo/bar.gif">
+ <a href="http://www.server.com/foo/bar.gif">
+
+ Using this option guarantees that recursive retrieval will not span
+hosts, even without `-H'. In simple cases it also allows downloads to
+"just work" without having to convert links.
+
+ This option is probably not very useful and might be removed in a
+future release.
+
+
+File: wget.info, Node: FTP Links, Prev: Relative Links, Up: Following Links
+
+4.5 Following FTP Links
+=======================
+
+The rules for FTP are somewhat specific, as it is necessary for them to
+be. FTP links in HTML documents are often included for purposes of
+reference, and it is often inconvenient to download them by default.
+
+ To have FTP links followed from HTML documents, you need to specify
+the `--follow-ftp' option. Having done that, FTP links will span hosts
+regardless of `-H' setting. This is logical, as FTP links rarely point
+to the same host where the HTTP server resides. For similar reasons,
+the `-L' options has no effect on such downloads. On the other hand,
+domain acceptance (`-D') and suffix rules (`-A' and `-R') apply
+normally.
+
+ Also note that followed links to FTP directories will not be
+retrieved recursively further.

+5 Time-Stamping
+***************
+
+One of the most important aspects of mirroring information from the
+Internet is updating your archives.
+
+ Downloading the whole archive again and again, just to replace a few
+changed files is expensive, both in terms of wasted bandwidth and money,
+and the time to do the update. This is why all the mirroring tools
+offer the option of incremental updating.
+
+ Such an updating mechanism means that the remote server is scanned in
+search of "new" files. Only those new files will be downloaded in the
+place of the old ones.
+
+ A file is considered new if one of these two conditions are met:
+
+ 1. A file of that name does not already exist locally.
+
+ 2. A file of that name does exist, but the remote file was modified
+ more recently than the local file.
+
+ To implement this, the program needs to be aware of the time of last
+modification of both local and remote files. We call this information
+the "time-stamp" of a file.
+
+ The time-stamping in GNU Wget is turned on using `--timestamping'
+(`-N') option, or through `timestamping = on' directive in `.wgetrc'.
+With this option, for each file it intends to download, Wget will check
+whether a local file of the same name exists. If it does, and the
+remote file is older, Wget will not download it.
+
+ If the local file does not exist, or the sizes of the files do not
+match, Wget will download the remote file no matter what the time-stamps
+say.

+File: wget.info, Node: Time-Stamping Usage, Next: HTTP Time-Stamping Internals, Up: Time-Stamping
+
+5.1 Time-Stamping Usage
+=======================
+
+The usage of time-stamping is simple. Say you would like to download a
+file so that it keeps its date of modification.
+
+ wget -S http://www.gnu.ai.mit.edu/
+
+ A simple `ls -l' shows that the time stamp on the local file equals
+the state of the `Last-Modified' header, as returned by the server. As
+you can see, the time-stamping info is preserved locally, even without
+`-N' (at least for HTTP).
+
+ Several days later, you would like Wget to check if the remote file
+has changed, and download it if it has.
+
+ wget -N http://www.gnu.ai.mit.edu/
+
+ Wget will ask the server for the last-modified date. If the local
+file has the same timestamp as the server, or a newer one, the remote
+file will not be re-fetched. However, if the remote file is more
+recent, Wget will proceed to fetch it.
+
+ The same goes for FTP. For example:
+
+ wget "ftp://ftp.ifi.uio.no/pub/emacs/gnus/*"
+
+ (The quotes around that URL are to prevent the shell from trying to
+interpret the `*'.)
+
+ After download, a local directory listing will show that the
+timestamps match those on the remote server. Reissuing the command
+with `-N' will make Wget re-fetch _only_ the files that have been
+modified since the last download.
+
+ If you wished to mirror the GNU archive every week, you would use a
+command like the following, weekly:
+
+ wget --timestamping -r ftp://ftp.gnu.org/pub/gnu/
+
+ Note that time-stamping will only work for files for which the server
+gives a timestamp. For HTTP, this depends on getting a `Last-Modified'
+header. For FTP, this depends on getting a directory listing with
+dates in a format that Wget can parse (*note FTP Time-Stamping
+Internals::).
+
+
+File: wget.info, Node: HTTP Time-Stamping Internals, Next: FTP Time-Stamping Internals, Prev: Time-Stamping Usage, Up: Time-Stamping
+
+5.2 HTTP Time-Stamping Internals
+================================
+
+Time-stamping in HTTP is implemented by checking of the `Last-Modified'
+header. If you wish to retrieve the file `foo.html' through HTTP, Wget
+will check whether `foo.html' exists locally. If it doesn't,
+`foo.html' will be retrieved unconditionally.
+
+ If the file does exist locally, Wget will first check its local
+time-stamp (similar to the way `ls -l' checks it), and then send a
+`HEAD' request to the remote server, demanding the information on the
+remote file.
+
+ The `Last-Modified' header is examined to find which file was
+modified more recently (which makes it "newer"). If the remote file is
+newer, it will be downloaded; if it is older, Wget will give up.(1)
+
+ When `--backup-converted' (`-K') is specified in conjunction with
+`-N', server file `X' is compared to local file `X.orig', if extant,
+rather than being compared to local file `X', which will always differ
+if it's been converted by `--convert-links' (`-k').
+
+ Arguably, HTTP time-stamping should be implemented using the
+`If-Modified-Since' request.
+
+ ---------- Footnotes ----------
+
+ (1) As an additional check, Wget will look at the `Content-Length'
+header, and compare the sizes; if they are not the same, the remote
+file will be downloaded no matter what the time-stamp says.
+
+
+File: wget.info, Node: FTP Time-Stamping Internals, Prev: HTTP Time-Stamping Internals, Up: Time-Stamping
+
+5.3 FTP Time-Stamping Internals
+===============================
+
+In theory, FTP time-stamping works much the same as HTTP, only FTP has
+no headers--time-stamps must be ferreted out of directory listings.
+
+ If an FTP download is recursive or uses globbing, Wget will use the
+FTP `LIST' command to get a file listing for the directory containing
+the desired file(s). It will try to analyze the listing, treating it
+like Unix `ls -l' output, extracting the time-stamps. The rest is
+exactly the same as for HTTP. Note that when retrieving individual
+files from an FTP server without using globbing or recursion, listing
+files will not be downloaded (and thus files will not be time-stamped)
+unless `-N' is specified.
+
+ Assumption that every directory listing is a Unix-style listing may
+sound extremely constraining, but in practice it is not, as many
+non-Unix FTP servers use the Unixoid listing format because most (all?)
+of the clients understand it. Bear in mind that RFC959 defines no
+standard way to get a file list, let alone the time-stamps. We can
+only hope that a future standard will define this.
+
+ Another non-standard solution includes the use of `MDTM' command
+that is supported by some FTP servers (including the popular
+`wu-ftpd'), which returns the exact time of the specified file. Wget
+may support this command in the future.

+6 Startup File
+**************
+
+Once you know how to change default settings of Wget through command
+line arguments, you may wish to make some of those settings permanent.
+You can do that in a convenient way by creating the Wget startup
+file--`.wgetrc'.
+
+ Besides `.wgetrc' is the "main" initialization file, it is
+convenient to have a special facility for storing passwords. Thus Wget
+reads and interprets the contents of `$HOME/.netrc', if it finds it.
+You can find `.netrc' format in your system manuals.
+
+ Wget reads `.wgetrc' upon startup, recognizing a limited set of
+commands.

+
+* Wgetrc Location:: Location of various wgetrc files.

+
+
+File: wget.info, Node: Wgetrc Location, Next: Wgetrc Syntax, Up: Startup File
+
+6.1 Wgetrc Location
+===================
+
+When initializing, Wget will look for a "global" startup file,
+`/usr/local/etc/wgetrc' by default (or some prefix other than
+`/usr/local', if Wget was not installed there) and read commands from
+there, if it exists.
+
+ Then it will look for the user's file. If the environmental variable
+`WGETRC' is set, Wget will try to load that file. Failing that, no
+further attempts will be made.
+
+ If `WGETRC' is not set, Wget will try to load `$HOME/.wgetrc'.
+
+ The fact that user's settings are loaded after the system-wide ones
+means that in case of collision user's wgetrc _overrides_ the
+system-wide wgetrc (in `/usr/local/etc/wgetrc' by default). Fascist
+admins, away!
+
+
+File: wget.info, Node: Wgetrc Syntax, Next: Wgetrc Commands, Prev: Wgetrc Location, Up: Startup File
+
+6.2 Wgetrc Syntax
+=================
+
+The syntax of a wgetrc command is simple:
+
+ variable = value
+
+ The "variable" will also be called "command". Valid "values" are
+different for different commands.
+
+ The commands are case-insensitive and underscore-insensitive. Thus
+`DIr__PrefiX' is the same as `dirprefix'. Empty lines, lines beginning
+with `#' and lines containing white-space only are discarded.
+
+ Commands that expect a comma-separated list will clear the list on an
+empty command. So, if you wish to reset the rejection list specified in
+global `wgetrc', you can do it with:
+
+ reject =
+
+
+File: wget.info, Node: Wgetrc Commands, Next: Sample Wgetrc, Prev: Wgetrc Syntax, Up: Startup File
+
+6.3 Wgetrc Commands
+===================
+
+The complete set of commands is listed below. Legal values are listed
+after the `='. Simple Boolean values can be set or unset using `on'
+and `off' or `1' and `0'. A fancier kind of Boolean allowed in some
+cases is the "lockable Boolean", which may be set to `on', `off',
+`always', or `never'. If an option is set to `always' or `never', that
+value will be locked in for the duration of the Wget
+invocation--command-line options will not override.
+
+ Some commands take pseudo-arbitrary values. ADDRESS values can be
+hostnames or dotted-quad IP addresses. N can be any positive integer,
+or `inf' for infinity, where appropriate. STRING values can be any
+non-empty string.
+
+ Most of these commands have direct command-line equivalents. Also,
+any wgetrc command can be specified on the command line using the
+`--execute' switch (*note Basic Startup Options::.)

+
+ ## You can use this file to change the default behaviour of wget or to
+ ## avoid having to type many many command-line options. This file does
+ ## not contain a comprehensive list of commands -- look at the manual
+ ## to find out what you can put into this file.
+ ##
+ ## Wget initialization file can reside in /usr/local/etc/wgetrc
+ ## (global, for all users) or $HOME/.wgetrc (for a single user).
+ ##
+ ## To use the settings in this file, you will have to uncomment them,

+ ## commented-out lines are the default values (e.g. "off").
+
+
+ ##
+ ## Global settings (useful for setting up in /usr/local/etc/wgetrc).
+ ## Think well before you change them, since they may reduce wget's
+ ## functionality, and make it behave contrary to the documentation:

+ # You can set retrieve quota for beginners by specifying a value
+ # optionally followed by 'K' (kilobytes) or 'M' (megabytes). The
+ # default quota is unlimited.
+ #quota = inf
+
+ # You can lower (or raise) the default number of retries when
+ # downloading a file (default is 20).
+ #tries = 20
+
+ # Lowering the maximum depth of the recursive retrieval is handy to
+ # prevent newbies from going too "deep" when they unwittingly start
+ # the recursive retrieval. The default is 5.
+ #reclevel = 5
+
+ # By default Wget uses "passive FTP" transfer where the client
+ # initiates the data connection to the server rather than the other
+ # way around. That is required on systems behind NAT where the client
+ # computer cannot be easily reached from the Internet. However, some
+ # firewalls software explicitly supports active FTP and in fact has
+ # problems supporting passive transfer. If you are in such
+ # environment, use "passive_ftp = off" to revert to active FTP.
+ #passive_ftp = off
+
+ # The "wait" command below makes Wget wait between every connection.
+ # If, instead, you want Wget to wait only between retries of failed
+ # downloads, set waitretry to maximum number of seconds to wait (Wget
+ # will use "linear backoff", waiting 1 second after the first failure
+ # on a file, 2 seconds after the second failure, etc. up to this max).
+ waitretry = 10
+
+
+ ##
+ ## Local settings (for a user to set in his $HOME/.wgetrc). It is
+ ## *highly* undesirable to put these settings in the global file, since
+ ## they are potentially dangerous to "normal" users.

+7 Examples
+**********
+
+The examples are divided into three sections loosely based on their
+complexity.
+
+* Menu:
+
+* Simple Usage:: Simple, basic usage of the program.
+* Advanced Usage:: Advanced tips.
+* Very Advanced Usage:: The hairy stuff.
+
+
+File: wget.info, Node: Simple Usage, Next: Advanced Usage, Up: Examples
+
+7.1 Simple Usage
+================
+
+ * Say you want to download a URL. Just type:
+
+ wget http://fly.srk.fer.hr/
+
+ * But what will happen if the connection is slow, and the file is
+ lengthy? The connection will probably fail before the whole file
+ is retrieved, more than once. In this case, Wget will try getting
+ the file until it either gets the whole of it, or exceeds the
+ default number of retries (this being 20). It is easy to change
+ the number of tries to 45, to insure that the whole file will
+ arrive safely:
+
+ wget --tries=45 http://fly.srk.fer.hr/jpg/flyweb.jpg
+
+ * Now let's leave Wget to work in the background, and write its
+ progress to log file `log'. It is tiring to type `--tries', so we
+ shall use `-t'.
+
+ wget -t 45 -o log http://fly.srk.fer.hr/jpg/flyweb.jpg &
+
+ The ampersand at the end of the line makes sure that Wget works in
+ the background. To unlimit the number of retries, use `-t inf'.
+
+ * The usage of FTP is as simple. Wget will take care of login and
+ password.
+
+ wget ftp://gnjilux.srk.fer.hr/welcome.msg
+
+ * If you specify a directory, Wget will retrieve the directory
+ listing, parse it and convert it to HTML. Try:
+
+ wget ftp://ftp.gnu.org/pub/gnu/
+ links index.html
+
+
+File: wget.info, Node: Advanced Usage, Next: Very Advanced Usage, Prev: Simple Usage, Up: Examples
+
+7.2 Advanced Usage
+==================
+
+ * You have a file that contains the URLs you want to download? Use
+ the `-i' switch:
+
+ wget -i FILE
+
+ If you specify `-' as file name, the URLs will be read from
+ standard input.
+
+ * Create a five levels deep mirror image of the GNU web site, with
+ the same directory structure the original has, with only one try
+ per document, saving the log of the activities to `gnulog':
+
+ wget -r http://www.gnu.org/ -o gnulog
+
+ * The same as the above, but convert the links in the HTML files to
+ point to local files, so you can view the documents off-line:
+
+ wget --convert-links -r http://www.gnu.org/ -o gnulog
+
+ * Retrieve only one HTML page, but make sure that all the elements
+ needed for the page to be displayed, such as inline images and
+ external style sheets, are also downloaded. Also make sure the
+ downloaded page references the downloaded links.
+
+ wget -p --convert-links http://www.server.com/dir/page.html
+
+ The HTML page will be saved to `www.server.com/dir/page.html', and
+ the images, stylesheets, etc., somewhere under `www.server.com/',
+ depending on where they were on the remote server.
+
+ * The same as the above, but without the `www.server.com/' directory.
+ In fact, I don't want to have all those random server directories
+ anyway--just save _all_ those files under a `download/'
+ subdirectory of the current directory.
+
+ wget -p --convert-links -nH -nd -Pdownload \
+ http://www.server.com/dir/page.html
+
+ * Retrieve the index.html of `www.lycos.com', showing the original
+ server headers:
+
+ wget -S http://www.lycos.com/
+
+ * Save the server headers with the file, perhaps for post-processing.
+
+ wget --save-headers http://www.lycos.com/
+ more index.html
+
+ * Retrieve the first two levels of `wuarchive.wustl.edu', saving them
+ to `/tmp'.
+
+ wget -r -l2 -P/tmp ftp://wuarchive.wustl.edu/
+
+ * You want to download all the GIFs from a directory on an HTTP
+ server. You tried `wget http://www.server.com/dir/*.gif', but that
+ didn't work because HTTP retrieval does not support globbing. In
+ that case, use:
+
+ wget -r -l1 --no-parent -A.gif http://www.server.com/dir/
+
+ More verbose, but the effect is the same. `-r -l1' means to
+ retrieve recursively (*note Recursive Download::), with maximum
+ depth of 1. `--no-parent' means that references to the parent
+ directory are ignored (*note Directory-Based Limits::), and
+ `-A.gif' means to download only the GIF files. `-A "*.gif"' would
+ have worked too.
+
+ * Suppose you were in the middle of downloading, when Wget was
+ interrupted. Now you do not want to clobber the files already
+ present. It would be:
+
+ wget -nc -r http://www.gnu.org/
+
+ * If you want to encode your own username and password to HTTP or
+ FTP, use the appropriate URL syntax (*note URL Format::).
+
+ wget ftp://hniksic:mypassword@unix.server.com/.emacs
+
+ Note, however, that this usage is not advisable on multi-user
+ systems because it reveals your password to anyone who looks at
+ the output of `ps'.
+
+ * You would like the output documents to go to standard output
+ instead of to files?
+
+ wget -O - http://jagor.srce.hr/ http://www.srce.hr/
+
+ You can also combine the two options and make pipelines to
+ retrieve the documents from remote hotlists:
+
+ wget -O - http://cool.list.com/ | wget --force-html -i -
+
+
+File: wget.info, Node: Very Advanced Usage, Prev: Advanced Usage, Up: Examples
+
+7.3 Very Advanced Usage
+=======================
+
+ * If you wish Wget to keep a mirror of a page (or FTP
+ subdirectories), use `--mirror' (`-m'), which is the shorthand for
+ `-r -l inf -N'. You can put Wget in the crontab file asking it to
+ recheck a site each Sunday:
+
+ crontab
+ 0 0 * * 0 wget --mirror http://www.gnu.org/ -o /home/me/weeklog
+
+ * In addition to the above, you want the links to be converted for
+ local viewing. But, after having read this manual, you know that
+ link conversion doesn't play well with timestamping, so you also
+ want Wget to back up the original HTML files before the
+ conversion. Wget invocation would look like this:
+
+ wget --mirror --convert-links --backup-converted \
+ http://www.gnu.org/ -o /home/me/weeklog
+
+ * But you've also noticed that local viewing doesn't work all that
+ well when HTML files are saved under extensions other than `.html',
+ perhaps because they were served as `index.cgi'. So you'd like
+ Wget to rename all the files served with content-type `text/html'
+ or `application/xhtml+xml' to `NAME.html'.
+
+ wget --mirror --convert-links --backup-converted \
+ --html-extension -o /home/me/weeklog \
+ http://www.gnu.org/
+
+ Or, with less typing:
+
+ wget -m -k -K -E http://www.gnu.org/ -o /home/me/weeklog

+
+8.1 Proxies
+===========
+
+"Proxies" are special-purpose HTTP servers designed to transfer data
+from remote servers to local clients. One typical use of proxies is
+lightening network load for users behind a slow connection. This is
+achieved by channeling all HTTP and FTP requests through the proxy
+which caches the transferred data. When a cached resource is requested
+again, proxy will return the data from cache. Another use for proxies
+is for companies that separate (for security reasons) their internal
+networks from the rest of Internet. In order to obtain information
+from the Web, their users connect and retrieve remote data using an
+authorized proxy.
+
+ Wget supports proxies for both HTTP and FTP retrievals. The
+standard way to specify proxy location, which Wget recognizes, is using
+the following environment variables:
+
+`http_proxy'
+ This variable should contain the URL of the proxy for HTTP
+ connections.
+
+`ftp_proxy'
+ This variable should contain the URL of the proxy for FTP
+ connections. It is quite common that HTTP_PROXY and FTP_PROXY are
+ set to the same URL.
+
+`no_proxy'
+ This variable should contain a comma-separated list of domain
+ extensions proxy should _not_ be used for. For instance, if the
+ value of `no_proxy' is `.mit.edu', proxy will not be used to
+ retrieve documents from MIT.
+
+ In addition to the environment variables, proxy location and settings
+may be specified from within Wget itself.
+
+`--no-proxy'
+`proxy = on/off'
+ This option and the corresponding command may be used to suppress
+ the use of proxy, even if the appropriate environment variables
+ are set.
+
+`http_proxy = URL'
+`ftp_proxy = URL'
+`no_proxy = STRING'
+ These startup file variables allow you to override the proxy
+ settings specified by the environment.
+
+ Some proxy servers require authorization to enable you to use them.
+The authorization consists of "username" and "password", which must be
+sent by Wget. As with HTTP authorization, several authentication
+schemes exist. For proxy authorization only the `Basic' authentication
+scheme is currently implemented.
+
+ You may specify your username and password either through the proxy
+URL or through the command-line options. Assuming that the company's
+proxy is located at `proxy.company.com' at port 8001, a proxy URL
+location containing authorization data might look like this:
+
+ http://hniksic:mypassword@proxy.company.com:8001/
+
+ Alternatively, you may use the `proxy-user' and `proxy-password'
+options, and the equivalent `.wgetrc' settings `proxy_user' and
+`proxy_password' to set the proxy username and password.

+
+8.2 Distribution
+================
+
+Like all GNU utilities, the latest version of Wget can be found at the
+master GNU archive site ftp.gnu.org, and its mirrors. For example,
+Wget 1.10.2 can be found at
+`ftp://ftp.gnu.org/pub/gnu/wget/wget-1.10.2.tar.gz'
+
+
+File: wget.info, Node: Mailing List, Next: Reporting Bugs, Prev: Distribution, Up: Various
+
+8.3 Mailing List
+================
+
+There are several Wget-related mailing lists, all hosted by SunSITE.dk.
+The general discussion list is at <wget@sunsite.dk>. It is the
+preferred place for bug reports and suggestions, as well as for
+discussion of development. You are invited to subscribe.
+
+ To subscribe, simply send mail to <wget-subscribe@sunsite.dk> and
+follow the instructions. Unsubscribe by mailing to
+<wget-unsubscribe@sunsite.dk>. The mailing list is archived at
+`http://www.mail-archive.com/wget%40sunsite.dk/' and at
+`http://news.gmane.org/gmane.comp.web.wget.general'.
+
+ The second mailing list is at <wget-patches@sunsite.dk>, and is used
+to submit patches for review by Wget developers. A "patch" is a
+textual representation of change to source code, readable by both
+humans and programs. The file `PATCHES' that comes with Wget covers
+the creation and submitting of patches in detail. Please don't send
+general suggestions or bug reports to `wget-patches'; use it only for
+patch submissions.
+
+ To subscribe, simply send mail to <wget-subscribe@sunsite.dk> and
+follow the instructions. Unsubscribe by mailing to
+<wget-unsubscribe@sunsite.dk>. The mailing list is archived at
+`http://news.gmane.org/gmane.comp.web.wget.patches'.
+
+
+File: wget.info, Node: Reporting Bugs, Next: Portability, Prev: Mailing List, Up: Various
+
+8.4 Reporting Bugs
+==================
+
+You are welcome to send bug reports about GNU Wget to
+<bug-wget@gnu.org>.
+
+ Before actually submitting a bug report, please try to follow a few
+simple guidelines.
+
+ 1. Please try to ascertain that the behavior you see really is a bug.
+ If Wget crashes, it's a bug. If Wget does not behave as
+ documented, it's a bug. If things work strange, but you are not
+ sure about the way they are supposed to work, it might well be a
+ bug.
+
+ 2. Try to repeat the bug in as simple circumstances as possible.
+ E.g. if Wget crashes while downloading `wget -rl0 -kKE -t5 -Y0
+ http://yoyodyne.com -o /tmp/log', you should try to see if the
+ crash is repeatable, and if will occur with a simpler set of
+ options. You might even try to start the download at the page
+ where the crash occurred to see if that page somehow triggered the
+ crash.
+
+ Also, while I will probably be interested to know the contents of
+ your `.wgetrc' file, just dumping it into the debug message is
+ probably a bad idea. Instead, you should first try to see if the
+ bug repeats with `.wgetrc' moved out of the way. Only if it turns
+ out that `.wgetrc' settings affect the bug, mail me the relevant
+ parts of the file.
+
+ 3. Please start Wget with `-d' option and send us the resulting
+ output (or relevant parts thereof). If Wget was compiled without
+ debug support, recompile it--it is _much_ easier to trace bugs
+ with debug support on.
+
+ Note: please make sure to remove any potentially sensitive
+ information from the debug log before sending it to the bug
+ address. The `-d' won't go out of its way to collect sensitive
+ information, but the log _will_ contain a fairly complete
+ transcript of Wget's communication with the server, which may
+ include passwords and pieces of downloaded data. Since the bug
+ address is publically archived, you may assume that all bug
+ reports are visible to the public.
+
+ 4. If Wget has crashed, try to run it in a debugger, e.g. `gdb `which
+ wget` core' and type `where' to get the backtrace. This may not
+ work if the system administrator has disabled core files, but it is
+ safe to try.

+
+8.5 Portability
+===============
+
+Like all GNU software, Wget works on the GNU system. However, since it
+uses GNU Autoconf for building and configuring, and mostly avoids using
+"special" features of any particular Unix, it should compile (and work)
+on all common Unix flavors.
+
+ Various Wget versions have been compiled and tested under many kinds
+of Unix systems, including GNU/Linux, Solaris, SunOS 4.x, OSF (aka
+Digital Unix or Tru64), Ultrix, *BSD, IRIX, AIX, and others. Some of
+those systems are no longer in widespread use and may not be able to
+support recent versions of Wget. If Wget fails to compile on your
+system, we would like to know about it.
+
+ Thanks to kind contributors, this version of Wget compiles and works
+on 32-bit Microsoft Windows platforms. It has been compiled
+successfully using MS Visual C++ 6.0, Watcom, Borland C, and GCC
+compilers. Naturally, it is crippled of some features available on
+Unix, but it should work as a substitute for people stuck with Windows.
+Note that Windows-specific portions of Wget are not guaranteed to be
+supported in the future, although this has been the case in practice
+for many years now. All questions and problems in Windows usage should
+be reported to Wget mailing list at <wget@sunsite.dk> where the
+volunteers who maintain the Windows-related features might look at them.
+
+
+File: wget.info, Node: Signals, Prev: Portability, Up: Various
+
+8.6 Signals
+===========
+
+Since the purpose of Wget is background work, it catches the hangup
+signal (`SIGHUP') and ignores it. If the output was on standard
+output, it will be redirected to a file named `wget-log'. Otherwise,
+`SIGHUP' is ignored. This is convenient when you wish to redirect the
+output of Wget after having started it.
+
+ $ wget http://www.gnus.org/dist/gnus.tar.gz &
+ ...
+ $ kill -HUP %%
+ SIGHUP received, redirecting output to `wget-log'.
+
+ Other than that, Wget will not try to interfere with signals in any
+way. `C-c', `kill -TERM' and `kill -KILL' should kill it alike.

+
+9.1 Robot Exclusion
+===================
+
+It is extremely easy to make Wget wander aimlessly around a web site,
+sucking all the available data in progress. `wget -r SITE', and you're
+set. Great? Not for the server admin.
+
+ As long as Wget is only retrieving static pages, and doing it at a
+reasonable rate (see the `--wait' option), there's not much of a
+problem. The trouble is that Wget can't tell the difference between the
+smallest static page and the most demanding CGI. A site I know has a
+section handled by a CGI Perl script that converts Info files to HTML on
+the fly. The script is slow, but works well enough for human users
+viewing an occasional Info file. However, when someone's recursive Wget
+download stumbles upon the index page that links to all the Info files
+through the script, the system is brought to its knees without providing
+anything useful to the user (This task of converting Info files could be
+done locally and access to Info documentation for all installed GNU
+software on a system is available from the `info' command).
+
+ To avoid this kind of accident, as well as to preserve privacy for
+documents that need to be protected from well-behaved robots, the
+concept of "robot exclusion" was invented. The idea is that the server
+administrators and document authors can specify which portions of the
+site they wish to protect from robots and those they will permit access.
+
+ The most popular mechanism, and the de facto standard supported by
+all the major robots, is the "Robots Exclusion Standard" (RES) written
+by Martijn Koster et al. in 1994. It specifies the format of a text
+file containing directives that instruct the robots which URL paths to
+avoid. To be found by the robots, the specifications must be placed in
+`/robots.txt' in the server root, which the robots are expected to
+download and parse.
+
+ Although Wget is not a web robot in the strictest sense of the word,
+it can downloads large parts of the site without the user's
+intervention to download an individual page. Because of that, Wget
+honors RES when downloading recursively. For instance, when you issue:
+
+ wget -r http://www.server.com/
+
+ First the index of `www.server.com' will be downloaded. If Wget
+finds that it wants to download more documents from that server, it will
+request `http://www.server.com/robots.txt' and, if found, use it for
+further downloads. `robots.txt' is loaded only once per each server.
+
+ Until version 1.8, Wget supported the first version of the standard,
+written by Martijn Koster in 1994 and available at
+`http://www.robotstxt.org/wc/norobots.html'. As of version 1.8, Wget
+has supported the additional directives specified in the internet draft
+`<draft-koster-robots-00.txt>' titled "A Method for Web Robots
+Control". The draft, which has as far as I know never made to an RFC,
+is available at `http://www.robotstxt.org/wc/norobots-rfc.txt'.
+
+ This manual no longer includes the text of the Robot Exclusion
+Standard.
+
+ The second, less known mechanism, enables the author of an individual
+document to specify whether they want the links from the file to be
+followed by a robot. This is achieved using the `META' tag, like this:
+
+ <meta name="robots" content="nofollow">
+
+ This is explained in some detail at
+`http://www.robotstxt.org/wc/meta-user.html'. Wget supports this
+method of robot exclusion in addition to the usual `/robots.txt'
+exclusion.
+
+ If you know what you are doing and really really wish to turn off the
+robot exclusion, set the `robots' variable to `off' in your `.wgetrc'.
+You can achieve the same effect from the command line using the `-e'
+switch, e.g. `wget -e robots=off URL...'.
+
+
+File: wget.info, Node: Security Considerations, Next: Contributors, Prev: Robot Exclusion, Up: Appendices
+
+9.2 Security Considerations
+===========================
+
+When using Wget, you must be aware that it sends unencrypted passwords
+through the network, which may present a security problem. Here are the
+main issues, and some solutions.
+
+ 1. The passwords on the command line are visible using `ps'. The best
+ way around it is to use `wget -i -' and feed the URLs to Wget's
+ standard input, each on a separate line, terminated by `C-d'.
+ Another workaround is to use `.netrc' to store passwords; however,
+ storing unencrypted passwords is also considered a security risk.
+
+ 2. Using the insecure "basic" authentication scheme, unencrypted
+ passwords are transmitted through the network routers and gateways.
+
+ 3. The FTP passwords are also in no way encrypted. There is no good
+ solution for this at the moment.
+
+ 4. Although the "normal" output of Wget tries to hide the passwords,
+ debugging logs show them, in all forms. This problem is avoided by
+ being careful when you send debug logs (yes, even when you send
+ them to me).

+GNU Wget is licensed under the GNU General Public License (GNU GPL),
+which makes it "free software". Please note that "free" in "free
+software" refers to liberty, not price. As some people like to point
+out, it's the "free" of "free speech", not the "free" of "free beer".
+
+ The exact and legally binding distribution terms are spelled out
+below. The GPL guarantees that you have the right (freedom) to run and
+change GNU Wget and distribute it to others, and even--if you
+want--charge money for doing any of those things. With these rights
+comes the obligation to distribute the source code along with the
+software and to grant your recipients the same rights and impose the
+same restrictions.
+
+ This licensing model is also known as "open source" because it,
+among other things, makes sure that all recipients will receive the
+source code along with the program, and be able to improve it. The GNU
+project prefers the term "free software" for reasons outlined at
+`http://www.gnu.org/philosophy/free-software-for-freedom.html'.

+10.1 GNU General Public License
+===============================
+
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+Preamble
+========
+
+The licenses for most software are designed to take away your freedom
+to share and change it. By contrast, the GNU General Public License is
+intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it in
+new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software,
+and (2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+ 0. This License applies to any program or other work which contains a
+ notice placed by the copyright holder saying it may be distributed
+ under the terms of this General Public License. The "Program",
+ below, refers to any such program or work, and a "work based on
+ the Program" means either the Program or any derivative work under
+ copyright law: that is to say, a work containing the Program or a
+ portion of it, either verbatim or with modifications and/or
+ translated into another language. (Hereinafter, translation is
+ included without limitation in the term "modification".) Each
+ licensee is addressed as "you".
+
+ Activities other than copying, distribution and modification are
+ not covered by this License; they are outside its scope. The act
+ of running the Program is not restricted, and the output from the
+ Program is covered only if its contents constitute a work based on
+ the Program (independent of having been made by running the
+ Program). Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the
+ notices that refer to this License and to the absence of any
+ warranty; and give any other recipients of the Program a copy of
+ this License along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy,
+ and you may at your option offer warranty protection in exchange
+ for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+ of it, thus forming a work based on the Program, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ a. You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b. You must cause any work that you distribute or publish, that
+ in whole or in part contains or is derived from the Program
+ or any part thereof, to be licensed as a whole at no charge
+ to all third parties under the terms of this License.
+
+ c. If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display
+ an announcement including an appropriate copyright notice and
+ a notice that there is no warranty (or else, saying that you
+ provide a warranty) and that users may redistribute the
+ program under these conditions, and telling the user how to
+ view a copy of this License. (Exception: if the Program
+ itself is interactive but does not normally print such an
+ announcement, your work based on the Program is not required
+ to print an announcement.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the
+ Program, and can be reasonably considered independent and separate
+ works in themselves, then this License, and its terms, do not
+ apply to those sections when you distribute them as separate
+ works. But when you distribute the same sections as part of a
+ whole which is a work based on the Program, the distribution of
+ the whole must be on the terms of this License, whose permissions
+ for other licensees extend to the entire whole, and thus to each
+ and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or
+ contest your rights to work written entirely by you; rather, the
+ intent is to exercise the right to control the distribution of
+ derivative or collective works based on the Program.
+
+ In addition, mere aggregation of another work not based on the
+ Program with the Program (or with a work based on the Program) on
+ a volume of a storage or distribution medium does not bring the
+ other work under the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+ under Section 2) in object code or executable form under the terms
+ of Sections 1 and 2 above provided that you also do one of the
+ following:
+
+ a. Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of
+ Sections 1 and 2 above on a medium customarily used for
+ software interchange; or,
+
+ b. Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a
+ medium customarily used for software interchange; or,
+
+ c. Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with
+ such an offer, in accord with Subsection b above.)
+
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete
+ source code means all the source code for all modules it contains,
+ plus any associated interface definition files, plus the scripts
+ used to control compilation and installation of the executable.
+ However, as a special exception, the source code distributed need
+ not include anything that is normally distributed (in either
+ source or binary form) with the major components (compiler,
+ kernel, and so on) of the operating system on which the executable
+ runs, unless that component itself accompanies the executable.
+
+ If distribution of executable or object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place counts as
+ distribution of the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense or distribute the Program is
+ void, and will automatically terminate your rights under this
+ License. However, parties who have received copies, or rights,
+ from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify
+ or distribute the Program or its derivative works. These actions
+ are prohibited by law if you do not accept this License.
+ Therefore, by modifying or distributing the Program (or any work
+ based on the Program), you indicate your acceptance of this
+ License to do so, and all its terms and conditions for copying,
+ distributing or modifying the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program
+ subject to these terms and conditions. You may not impose any
+ further restrictions on the recipients' exercise of the rights
+ granted herein. You are not responsible for enforcing compliance
+ by third parties to this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent
+ issues), conditions are imposed on you (whether by court order,
+ agreement or otherwise) that contradict the conditions of this
+ License, they do not excuse you from the conditions of this
+ License. If you cannot distribute so as to satisfy simultaneously
+ your obligations under this License and any other pertinent
+ obligations, then as a consequence you may not distribute the
+ Program at all. For example, if a patent license would not permit
+ royalty-free redistribution of the Program by all those who
+ receive copies directly or indirectly through you, then the only
+ way you could satisfy both it and this License would be to refrain
+ entirely from distribution of the Program.
+
+ If any portion of this section is held invalid or unenforceable
+ under any particular circumstance, the balance of the section is
+ intended to apply and the section as a whole is intended to apply
+ in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of
+ any such claims; this section has the sole purpose of protecting
+ the integrity of the free software distribution system, which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is
+ willing to distribute software through any other system and a
+ licensee cannot impose that choice.
+
+ This section is intended to make thoroughly clear what is believed
+ to be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+ certain countries either by patents or by copyrighted interfaces,
+ the original copyright holder who places the Program under this
+ License may add an explicit geographical distribution limitation
+ excluding those countries, so that distribution is permitted only
+ in or among countries not thus excluded. In such case, this
+ License incorporates the limitation as if written in the body of
+ this License.
+
+ 9. The Free Software Foundation may publish revised and/or new
+ versions of the General Public License from time to time. Such
+ new versions will be similar in spirit to the present version, but
+ may differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Program specifies a version number of this License which applies
+ to it and "any later version", you have the option of following
+ the terms and conditions either of that version or of any later
+ version published by the Free Software Foundation. If the Program
+ does not specify a version number of this License, you may choose
+ any version ever published by the Free Software Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, write to the
+ author to ask for permission. For software which is copyrighted
+ by the Free Software Foundation, write to the Free Software
+ Foundation; we sometimes make exceptions for this. Our decision
+ will be guided by the two goals of preserving the free status of
+ all derivatives of our free software and of promoting the sharing
+ and reuse of software generally.
+
+ NO WARRANTY
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
+ WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+ LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+ HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
+ WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
+ NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
+ FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
+ QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+ PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
+ SERVICING, REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
+ MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
+ LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+ INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+ INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+ DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
+ OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
+ OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
+ ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+Appendix: How to Apply These Terms to Your New Programs
+=======================================================
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.
+ Copyright (C) YYYY NAME OF AUTHOR
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
+
+ Also add information on how to contact you by electronic and paper
+mail.
+
+ If the program is interactive, make it output a short notice like
+this when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19YY NAME OF AUTHOR
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+ The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License. Of course, the
+commands you use may be called something other than `show w' and `show
+c'; they could even be mouse-clicks or menu items--whatever suits your
+program.
+
+ You should also get your employer (if you work as a programmer) or
+your school, if any, to sign a "copyright disclaimer" for the program,
+if necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ SIGNATURE OF TY COON, 1 April 1989
+ Ty Coon, President of Vice
+
+ This General Public License does not permit incorporating your
+program into proprietary programs. If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library. If this is what you want to do, use the
+GNU Lesser General Public License instead of this License.

+10.2 GNU Free Documentation License
+===================================
+
+ Version 1.2, November 2002
+
+ Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ 0. PREAMBLE
+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book.
+ We recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided for under this License. Any other
+ attempt to copy, modify, sublicense or distribute the Document is
+ void, and will automatically terminate your rights under this
+ License. However, parties who have received copies, or rights,
+ from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation.
+
+10.2.1 ADDENDUM: How to use this License for your documents
+-----------------------------------------------------------
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.
