.el .IP "\f(CWplatform\fR" 6
.IX Item "platform"
If \f(CW\*(C`$^O=~/MSWin(32|64)$/i\*(C'\fR is true we know that we're on
Windows and we set the global variable \f(CW$::_platform_\fR to \f(CW\*(C`win32\*(C'\fR.
Otherwise we call \f(CW\*(C`config.guess\*(C'\fR.  The output of \f(CW\*(C`config.guess\*(C'\fR
is filtered as described below.
.Sp
\&\s-1CPU\s0 type is determined by a regexp.  And it's necessary to
\&\f(CW\*(C`s/i.86/i386/\*(C'\fR.
.Sp
For \s-1OS\s0 we need a list because we probably have something like
\&\f(CW\*(C`linux\-gnu\*(C'\fR but we need \f(CW\*(C`linux\*(C'\fR.  This list might/should contain OSs
which are not currently supported.  The list currently supports all
platforms supported by TeX Live 2007 plus Cygwin.
.Sp
If a particular platform is not found in this list we use the regexp
\&\f(CW\*(C`/.*\-(.*$)/\*(C'\fR as a last resort and hope it provides something useful.
.Sp
The result is stored in a global variable \f(CW$::_platform_\fR.  If you call
\&\f(CW\*(C`platform\*(C'\fR repeatedly, only the first call of \f(CW\*(C`platform\*(C'\fR will access
the \s-1HD/CD/DVD\s0.
.ie n .IP """platform_desc($platform)""" 6
.el .IP "\f(CWplatform_desc($platform)\fR" 6
.IX Item "platform_desc($platform)"
Return a string which describes a particular platform.  Same as in TeX
Live 2007 but NetBSD added.
.ie n .IP """win32""" 6
.el .IP "\f(CWwin32\fR" 6
.IX Item "win32"
Return \f(CW1\fR if platform is Windows and \f(CW0\fR otherwise.
.ie n .IP """unix""" 6
.el .IP "\f(CWunix\fR" 6
.IX Item "unix"
Return \f(CW1\fR if platform is \s-1UNIX\s0 and \f(CW0\fR otherwise.
.Sh "System Tools"
.IX Subsection "System Tools"
.ie n .IP """getenv($string)""" 6
.el .IP "\f(CWgetenv($string)\fR" 6
.IX Item "getenv($string)"
Get an environment variable.  It is assumed that the environment
variable contains a path.  On Windows all backslashes are replaced by
forward slashes as required by Perl.  If this behavior is not desired,
use \f(CW$ENV{"$variable"}\fR instead.  \f(CW0\fR is returned if the
environment variable is not set.
.ie n .IP """which($string)""" 6
.el .IP "\f(CWwhich($string)\fR" 6
.IX Item "which($string)"
\&\f(CW\*(C`which\*(C'\fR does the same as the \s-1UNIX\s0 command \f(CWwhich(1)\fR, but it is
supposed to work on Windows too.  On Windows we have to try all the
extensions given in the \f(CW\*(C`PATHEXT\*(C'\fR environment variable.  We also try
without appending an extension because if \f(CW$string\fR comes from an
environment variable, an extension might aleady be present.
.ie n .IP """program_exists($program)""" 6
.el .IP "\f(CWprogram_exists($program)\fR" 6
.IX Item "program_exists($program)"
Return \f(CW1\fR if \f(CW$program\fR is in \f(CW\*(C`PATH\*(C'\fR and \f(CW0\fR otherwise.
.ie n .IP """get_system_tmpdir""" 6
.el .IP "\f(CWget_system_tmpdir\fR" 6
.IX Item "get_system_tmpdir"
Evaluate the environment variables \f(CW\*(C`TMPDIR\*(C'\fR, \f(CW\*(C`TMP\*(C'\fR, and \f(CW\*(C`TEMP\*(C'\fR in
order to find the system temporary directory.
.Sh "File Utulities"
.IX Subsection "File Utulities"
.ie n .IP """dirname($path)""" 6
.el .IP "\f(CWdirname($path)\fR" 6
.IX Item "dirname($path)"
Return \f(CW$path\fR with its trailing \f(CW\*(C`/component\*(C'\fR removed.
.ie n .IP """basename($path)""" 6
.el .IP "\f(CWbasename($path)\fR" 6
.IX Item "basename($path)"
Return \f(CW$path\fR with any leading directory components removed.
.ie n .IP """dirname_and_basename($path)""" 6
.el .IP "\f(CWdirname_and_basename($path)\fR" 6
.IX Item "dirname_and_basename($path)"
Return both \f(CW\*(C`dirname\*(C'\fR and \f(CW\*(C`basename\*(C'\fR.  Example:
.Sp
.Vb 1
\&  ($dirpart,$filepart) = dirname_and_basename ($path);
.Ve
.ie n .IP """mkdirhier($path, [$mode])""" 6
.el .IP "\f(CWmkdirhier($path, [$mode])\fR" 6
.IX Item "mkdirhier($path, [$mode])"
The function \f(CW\*(C`mkdirhier\*(C'\fR does the same as the \s-1UNIX\s0 command \f(CW\*(C`mkdir \-p\*(C'\fR.
The optional parameter sets the permission flags.
.ie n .IP """copy($file, $target_dir)""" 6
.el .IP "\f(CWcopy($file, $target_dir)\fR" 6
.IX Item "copy($file, $target_dir)"
Copy file \f(CW$file\fR to directory \f(CW$target_dir\fR.  No external programs
are involved.  Since we need \f(CW\*(C`sysopen()\*(C'\fR, the Perl module \f(CW\*(C`Fcntl.pm\*(C'\fR
is required.  The time stamps are preserved and symlinks are created
on \s-1UNIX\s0 systems.  On Windows, \f(CW\*(C`(\-l $file)\*(C'\fR will certainly never
return '\f(CW\*(C`true\*(C'\fR' and symlinks will be copied as regular files.
.Sp
\&\f(CW\*(C`copy\*(C'\fR invokes \f(CW\*(C`mkdirhier\*(C'\fR if target directories do not exist.
Files have mode \f(CW0777\fR\-\fIumask\fR if they are executable and
\&\f(CW0666\fR\-\fIumask\fR otherwise.
.ie n .IP """install_packages($from_tlpdb, $to_tlpdb, $what, $opt_src, $opt_doc)""" 6
.el .IP "\f(CWinstall_packages($from_tlpdb, $to_tlpdb, $what, $opt_src, $opt_doc)\fR" 6
.IX Item "install_packages($from_tlpdb, $to_tlpdb, $what, $opt_src, $opt_doc)"
Installs the list of packages found in \f(CW@$what\fR (a ref to a list) into
the \s-1TLPDB\s0 given by \f(CW$to_tlpdb\fR. Information on files are taken from
the \s-1TLPDB\s0 \f(CW$from_tlpdb\fR.
.Sp
\&\f(CW$opt_src\fR and \f(CW$opt_doc\fR specify whether srcfiles and docfiles should be
installed (currently implemented only for installation from \s-1DVD\s0).
.ie n .IP """install_package($what, $filelistref, $target, $platform)""" 6
.el .IP "\f(CWinstall_package($what, $filelistref, $target, $platform)\fR" 6
.IX Item "install_package($what, $filelistref, $target, $platform)"
This function installs the files given in @$filelistref from \f(CW$what\fR
into \f(CW$target\fR.
.Sp
If \f(CW$what\fR is a reference to a list of files then these files are
assumed to be readable and are copied to \f(CW$target\fR, creating dirs on
the way. In this case the list \f(CW@$filelistref\fR is not taken into
account.
.Sp
If \f(CW$what\fR starts with \f(CW\*(C`http://\*(C'\fR or \f(CW\*(C`ftp://\*(C'\fR then \f(CW$what\fR is
downloaded from the net and piped through c<lzmadec> and \f(CW\*(C`tar\*(C'\fR.
.Sp
If \f(CW$what\fR ends with \f(CW\*(C`.tar.lzma\*(C'\fR (but does not start with \f(CW\*(C`http://\*(C'\fR or

Sets up the global \f(CW$::progs\fR hash containing the pathes to the 
programs \f(CW\*(C`wget\*(C'\fR, \f(CW\*(C`tar\*(C'\fR, \f(CW\*(C`lzmadec\*(C'\fR. The \f(CW$bindir\fR argument specifies
the path to the location of the \f(CW\*(C`lzmadec\*(C'\fR binaries, the \f(CW$platform\fR
gives the extension for the \f(CW\*(C`lzmadec\*(C'\fR binary.

Try to download the file given in \f(CW$relpath\fR from either \f(CW$TeXLiveURL\fR
or \f(CW\*(C`TeXLiveAlternativeURL\*(C'\fR into \f(CW$destination\fR, which can be either 
a filename of simply \f(CW\*(C`|\*(C'\fR. In the latter case a file handle is returned.
.Sp
The optional argument \f(CW$progs\fR is a reference to a hash giving full pathes 
to the respective programs, at least \f(CW\*(C`wget\*(C'\fR. In case that \f(CW$progs\fR is not
given the \f(CW%::progs\fR is consulted, and if this also does not exist we
try \*(L"wget\*(R".
.Sp
Downloading honors two environment variables \f(CW\*(C`TL_DOWNLOAD_PROGRAM\*(C'\fR and
\&\f(CW\*(C`TL_DOWNLOAD_ARGS\*(C'\fR. The former overrides \f(CW\*(C`wget\*(C'\fR (or what is given in the
\&\f(CW$progs\fR argument, the latter overrides the default wget arguments
given in \f(CW$TeXLive::TLConfig::DefaultWgetArgs\fR. 
.Sp
\&\f(CW\*(C`TL_DOWNLOAD_ARGS\*(C'\fR must be set up in a way that the place the output should
go to is the first argument after the \f(CW\*(C`TL_DOWNLOAD_ARGS\*(C'\fR. Use with care.

.IX Item "media"
Return media type.  Either \f(CW\*(C`CD\*(C'\fR, \f(CW\*(C`DVD\*(C'\fR, or \f(CW\*(C`NET\*(C'\fR.
.Sp
The result is stored in a global variable \f(CW$::_media_\fR.  If you call
\&\f(CW\*(C`media\*(C'\fR repeatedly, only the first call of \f(CW\*(C`media\*(C'\fR will access the
\&\s-1CD/DVD\s0.
.ie n .IP """initialize_installer""" 6
.el .IP "\f(CWinitialize_installer\fR" 6
.IX Item "initialize_installer"
The function \f(CW\*(C`initialize_installer\*(C'\fR calls \f(CW\*(C`media\*(C'\fR and \f(CW\*(C`platform\*(C'\fR in
order to set the variables \f(CW$::_media_\fR and \f(CW$::_platform_\fR.
.Sp
Note that \f(CW$0\fR contains backslashes as path separators on Windows.
.Sp
Repeatedly calls to \f(CW\*(C`media\*(C'\fR or \f(CW\*(C`platform\*(C'\fR do not access the \s-1CD/DVD\s0
again.
.ie n .IP """make_var_skeleton($prefix)""" 6
.el .IP "\f(CWmake_var_skeleton($prefix)\fR" 6

.PD
These three functions create \f(CW\*(C`fmtutil.cnf\*(C'\fR, \f(CW\*(C`updmap.cfg\*(C'\fR, and
\&\f(CW\*(C`language.dat\*(C'\fR, respectively, in \f(CW$dest\fR (which by default is below
\&\f(CW$TEXMFSYSVAR\fR).  These functions merge the information present in the
\&\s-1TLPDB\s0 \f(CW$tlpdb\fR (formats, maps, hyphenations) with local configuration
additions: \f(CW$localconf\fR.
.Sp
Currently the \*(L"merging\*(R" is done trivially by appending the content of
the local configuration files at the end of the file. This should be
improved (checking for duplicates).
.Sh "Miscellaneous"
.IX Subsection "Miscellaneous"
Ideas from Fabrice Popineau's \f(CW\*(C`FileUtils.pm\*(C'\fR.
.ie n .IP """sort_uniq(@list)""" 6
.el .IP "\f(CWsort_uniq(@list)\fR" 6
.IX Item "sort_uniq(@list)"
The \f(CW\*(C`sort_uniq\*(C'\fR function sorts the given array and throws away multiple
occurrences of elements. It returns a sorted and unified array.
.ie n .IP """push_uniq(\e@list, @items)""" 6
.el .IP "\f(CWpush_uniq(\e@list, @items)\fR" 6
.IX Item "push_uniq(@list, @items)"
The \f(CW\*(C`push_uniq\*(C'\fR function pushes the last elements on the list referenced
by the first argument.
.ie n .IP """member($item, @list)""" 6
.el .IP "\f(CWmember($item, @list)\fR" 6

The \f(CW\*(C`member\*(C'\fR function returns true if the the first argument is contained
in the list of the remaining arguments.
.ie n .IP """texdir_check($texdir)""" 6
.el .IP "\f(CWtexdir_check($texdir)\fR" 6

Test whether installation with \s-1TEXDIR\s0 set to \f(CW$texdir\fR would succeed due to
writing permissions.
.ie n .IP """tllog($type, $rest, ...)""" 6
.el .IP "\f(CWtllog($type, $rest, ...)\fR" 6
.IX Item "tllog($type, $rest, ...)"
Debugging output is controlled by 2 global variables: \f(CW$::LOGLEVELTERMINAL\fR
for the output to the terminal, and \f(CW$::LOGLEVELFILE\fR for the output to
the log file (whose filehandle should be saved in \f(CW$::LOGFILE\fR).
.Sp
If the first argument of \f(CW\*(C`tllog\*(C'\fR is less or equal to the respective
threshold the message is issued to \s-1STDERR\s0 and log file, respectively.
.Sp
If \f(CW$::LOGFILE\fR is not defined logging to a log file is completely disabled.
.Sp
Predefined levels of debugging are: \f(CW$::LOG_NORMAL\fR, \f(CW$::LOG_DEBUG\fR, \f(CW$::LOG_DDEBUG\fR,
and \f(CW$::LOG_DDDEBUG\fR with increasing level of detailedness.
.Sp
Note that all TeXLive modules to logging with \f(CW$::LOG_DDDEBUG\fR!
.Sp
By default the threshold for logging to the log file is \f(CW$::LOG_DEBUG\fR, and
the one for the terminal \f(CW$::LOG_NORMAL\fR.
.Sp
If you want to disable logging set the respective thershold to \f(CW$::LOG_ZERO\fR.
.ie n .IP """kpsewhich($varname)""" 6

.IX Item "kpsewhich($varname)"
This function expands the variable name using kpsewhich. The variable
name should not have a leading $. The kpsewhich binary has to be in
the path.
.ie n .IP """conv_to_win_path($path)""" 6
.el .IP "\f(CWconv_to_win_path($path)\fR" 6
.IX Item "conv_to_win_path($path)"
This function returns a \*(L"windowsified\*(R" path, i.e., replacing all forward
slashes to backslashes, and adding additional " around (in case of spaces
in \f(CW$path\fR). Furthermore it makes the path absolute. So if \f(CW$path\fR does not
start with an arbitrary char followed by : we add the output of `cd`.
