+=head1 NAME
+
+install-tl - TeX Live cross-platform installer
+
+=head1 SYNOPSIS
+
+install-tl [I<option>]...
+
+install-tl.bat [I<option>]...
+
+=head1 DESCRIPTION
+
+This installer creates a runnable TeX Live installation from various
+media, including over the network. The installer works across all
+platforms supported by TeX Live. For information on initially
+downloading the TeX Live, see L<http://tug.org/texlive/acquire.html>.
+
+The basic idea of TeX Live installation is to choose one of the
+top-level I<schemes>, each of which is defined as a different set of
+I<collections> and I<packages>, where a collection is a set of packages,
+and a package is what contains actual files.
+
+Within the installer, you can choose a scheme, and further customize the
+set of collections to install, but not the set of the packages. To do
+that, use C<tlmgr> (reference below) after the initial installation is
+completely.
+
+The default is C<scheme-full>, to install everything, and this is highly
+recommended.
+
+=head1 REFERENCES
+
+Post-installation configuration, package updates, and much more, are
+handled through B<tlmgr>(1), the TeX Live Manager
+(L<http://tug.org/texlive/tlmgr.html>).
+
+The most up-to-date version of this documentation is on the Internet at
+L<http://tug.org/texlive/doc/install-tl.html>.
+
+For the full documentation of TeX Live, see
+L<http://tug.org/texlive/doc>.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-gui> [[=]I<module>]
+
+If no I<module> is given starts the C<perltk> (see below) GUI installer.
+
+If I<module> is given loads the given installer module. Currently the
+following modules are supported:
+
+=over 8
+
+=item C<text>
+
+The text mode user interface which is the default on Unix systems, and
+can be forced with by giving C<text> as I<module>, or with the C<-no-gui>
+switch.
+
+=item C<wizard>
+
+The wizard mode user interface asking only a few questions before installing
+all of TeX Live. This is the default on Windows systems.
+
+=item C<perltk>
+
+The all-in-one GUI installer.
+It can also be selected by giving the C<-gui> option without any I<module>.
+
+=back
+
+The C<perltk> and C<wizard> modules, and thus also when calling with a
+simple C<-gui> (without I<module>) requires
+the Perl/Tk module (L<http://tug.org/texlive/distro.html#perltk>); if
+Perl/Tk is not available, installation continues in text mode.
+
+
+=item B<-no-gui>
+
+Use the text mode installer (default except on Windows).
+
+=item B<-lang> I<llcode>
+
+(only for GUI installer) If possible, start the installer translated into
+the language specified by the 2-letter (ISO 639-1) language code (with
+the exception for selecting simplified or traditional Chinese).
+Currently supported
+languages: English (en, default), Czech (cs), German (de), French (fr),
+Italian (it), Dutch (nl), Polish (pl), Russian (ru), Slovak (sk),
+Slovenian (sl), Serbian (sr), Vietnamese (vi), simplified Chinese
+(zh-cn), and traditional Chinese (zh-tw).
+
+=item B<-repository> I<url|path>
+
+Specify the package repository to be used as the source of the
+installation, either a local directory via C</path/to/directory> or a
+C<file:/> url, or a network location via a C<http://> or C<ftp://> url.
+(No other protocols are supported.)
+
+The default is to pick a mirror automatically, using
+L<http://mirror.ctan.org/systems/texlive/tlnet>; the chosen mirror is
+used for the entire download. You can use the special argument C<ctan>
+as an abbreviation for this. See L<http://ctan.org> for more about CTAN
+and its mirrors.
+
+If the repository is on the network, trailing C</> characters and/or
+trailing C</tlpkg> and C</archive> components are ignored. For example,
+you could choose a particular CTAN mirror with something like this:
+
+ -repository http://ctan.example.org/its/ctan/dir/systems/texlive/tlnet
+
+Of course a real hostname and its particular top-level CTAN path
+have to be specified. The list of CTAN mirrors is available at
+L<http://ctan.org/mirrors>.
+
+If the repository is local, the installation type (compressed or live) is
+automatically determined, by checking for the presence of a
+C<archive> directory relative to the root. Compressed is
+preferred if both are available, since it is faster. Here's an example
+of using a local directory:
+
+ -repository /local/TL/repository
+
+After installation is complete, you can use that installation as the
+repository for another installation. If you chose to install less than
+the full scheme containing all packages, the list of available schemes
+will be adjusted accordingly.
+
+For backward compatibility and convenience, C<--location> and C<--repo>
+are accepted as aliases for this option.
+
+=item B<-all-options>
+
+Normally options not regarding the current platform are not shown.
+Giving this cmd line option allows to configure settings in the
+final tlpdb that do not have any immediate effect.
+
+=item B<-custom-bin> I<path>
+
+If you have built your own binaries for your system (probably because
+your platform was not supported by TeX Live out of the box), this option
+allows you to give the I<path> to a directory where the binaries for the
+current system are present. The installation will continue as usual, but
+at the end all files from I<path> are copied over to C<bin/custom> in
+your installation folder and this directory will be added to the path
+for the post-install actions.
+
+=item B<-debug-translation>
+
+In GUI mode, this switch makes C<tlmgr> report any missing, or more
+likely untranslated, messages to standard error. Helpful for
+translators to see what remains to be done.
+
+=item B<--help>, B<-help>, B<-?>
+
+Display this help and exit.
+
+=item B<-logfile> I<file>
+
+Write both all messages (informational, debugging, warnings) to I<file>,
+in addition to standard output or standard error.
+
+If this option is not given, the installer will create a log file
+in the root of the writable installation tree,
+for example, C</usr/local/texlive/YYYY/install-tl.log> for the I<YYYY>
+release.
+
+=item B<-force-platform> I<platform>
+
+Instead of auto-detecting the current platform, use I<platform>.
+Binaries for this platform must be present and they must actually be
+runnable, or installation will fail. C<-force-arch> is a synonym.
+
+=item B<-no-cls>
+
+(only for text mode installer) do not clear the screen when entering
+a new menu (for debugging purposes).
+
+=item B<-non-admin>
+
+For Windows only: configure for the current user, not for all users.
+
+=item B<--persistent-downloads>
+
+=item B<--no-persistent-downloads>
+
+For net installs, activating this option makes the installer try to set up a
+persistent connection using the Net::LWP Perl module.
+This opens only one connection between your computer and the server
+per session and reuses it, instead of initiating a new download for
+each package.
+
+This option is turned on by default, and the installation program will
+fall back to using C<wget> if this is not possible. To disable usage of
+LWP and persistent connections, use C<--no-persistent-downloads>.
+
+=item B<-portable>
+
+Install for portable use. This option minimazes the impact on the host
+system making TeX Live self-contained in a single directory and
+usable from portable drives. See section B<PORTABLE USE> below.
+
+=item B<-print-platform>
+
+Print the TeX Live identifier for the detected platform
+(hardware/operating system) combination to standard output, and exit.
+C<-print-arch> is a synonym.
+
+=item B<-profile> I<profile>
+
+Load the I<profile> file for repeated installations on different systems.
+A I<profile> contains the values of all necessary variable for the
+installation. After normal installation has finished a profile for that
+exact installation is written into DEST/tlpkg/texlive.profile. That file
+can be used to do the exact same installation on a different computer.
+
+You can also hand-craft such a profile starting from a generated one
+by changing some values. Normally a profile has to contain the value 1 for
+each collection that should be installed, even if the scheme is specified.
+That follows from the logic of the installer that you first select a scheme
+and then can change the actual collections being installed.
+
+There is one exception to this: If the profile contains a variable for
+C<selected_scheme> and I<no> collection variable is defined in the
+profile, then the collections which the specified scheme requires are
+installed. Thus, a simple line C<selected_scheme scheme-medium>
+together with the definitions of the paths (C<TEXDIR>,
+C<TEXMFHOME>, C<TEXMFLOCAL>, C<TEXMFSYSCONFIG>, C<TEXMFSYSVAR>) suffices
+to install the medium scheme with all default options.
+
+=item B<-q>
+
+Omit normal informational messages.
+
+=item B<-scheme> I<scheme>
+
+Schemes are the highest level of package grouping in TeX Live; the
+default is to use the C<full> scheme, which includes everything. This
+option overrides that default. You can change the scheme again before
+the actual installation with the usual menu. The I<scheme> argument may
+optionally have a prefix C<scheme->. The list of supported scheme names
+depends on what your package repository provides; see the interactive
+menu list.
+
+=item B<-v>
+
+Include debugging messages; repeat for maximum debugging, as in C<-v
+-v>. (Further repeats are accepted but ignored.)
+
+=item B<--version>, B<-version>
+
+Output version information and exit.
+If C<-v> has been given the revisions of the used modules are reported, too.
+
+=back
+
+As usual, all options can be specified with either C<-> or C<-->, and
+arguments can be separated from their options by either a space or C<=>.
+
+=head1 PORTABLE USE
+
+The root directory of a TeX Live installation contains a shell script
+C<tl-portable> and a DOS batch file C<tl-portable.bat> which start up a
+new shell (command prompt), in which TeX Live can be run self-contained.
+
+When running these scripts from a non-writable medium, some preparation
+of the host system is done on the first run, in the host directory
+C<~/.tlportableYYYY>. Otherwise, the host system is not touched.
