=head1 NAME

C<TeXLive::TLConfig> -- TeX Live Configuration module

=head1 SYNOPSIS

  use TeXLive::TLConfig;

=head1 DESCRIPTION

The L<TeXLive::TLConfig> module contains definitions of variables 
configuring all of TeX Live.

=over 4

=head1 EXPORTED VARIABLES

All of the following variables are pulled into the callers namespace,
i.e., are declared with C<EXPORT> (and C<EXPORT_OK>).

=item C<@TeXLive::TLConfig::MetaCategories>

The list of meta categories, i.e., those categories whose packages only
depend on other packages, but don't ship any files. Currently 
C<Collection> and <Scheme>.

=item C<@TeXLive::TLConfig::NormalCategories>

The list of normal categories, i.e., those categories whose packages do
ship files. Currently C<TLCore>, C<Package>, C<ConTeXt>.

=item C<@TeXLive::TLConfig::Categories>

The list of all categories, i.e., the union of the above.

=item C<$TeXLive::TLConfig::CategoriesRegexp>

A regexp matching any category.

=item C<$TeXLive::TLConfig::DefaultCategory>

The default category used when creating new packages.

=item C<$TeXLive::TLConfig::InfraLocation>

The subdirectory with various infrastructure files (C<texlive.tlpdb>,
tlpobj files, ...) relative to the root of the installation; currently
C<tlpkg>.

=item C<$TeXLive::TLConfig::BlockSize>

The assumed block size, currently 4k.

=item C<$TeXLive::TLConfig::Archive>
=item C<$TeXLive::TLConfig::TeXLiveURL>

These values specify where to find packages.

=item C<$TeXLive::TLConfig::TeXLiveServerURL>
=item C<$TeXLive::TLConfig::TeXLiveServerPath>

C<TeXLiveURL> is concatenated from these values, with a string between.
The defaults are respectively, C<http://mirror.ctan.org> and
C<systems/texlive/tlnet/>.

=item C<@TeXLive::TLConfig::CriticalPackagesList>
=item C<@TeXLive::TLConfig::CriticalPackagesRegexp>

A list of all those packages which we do not update regularly since they
are too central, currently texlive.infra and (for Windows) tlperl.win32.

=item C<$TeXLive::TLConfig::RelocTree>

The texmf-tree name that can be relocated, defaults to C<texmf-dist>.

=item C<$TeXLive::TLConfig::RelocPrefix>

The string that replaces the C<RelocTree> in the tlpdb if a package is
relocated, defaults to C<RELOC>".

=back

=head1 SEE ALSO

All the other TeX Live modules and scripts, especially C<tlmgr> and
C<install-tl>, and the documentation in the repository:
C<Master/tlpkg/doc/>.
