=item C<< TeXLive::TLPDB->new >>

=item C<< TeXLive::TLPDB->new( [root => "$path"] ) >>

C<< TeXLive::TLPDB->new >> creates a new C<TLPDB> object. If the
argument C<root> is given it will be initialized from the respective
location within $path. If
C<$path> begins with C<http://> or C<ftp://>, the program C<wget>
is used to download the file.

=pod

=item C<< $tlpdb->add_tlpobj($tlpobj) >>

The C<add_tlpobj> adds an object of the type TLPOBJ to the TLPDB.

=cut

Returns an array of package names depending on $pkg.

The C<from_file> function initializes the C<TLPDB> in case the
root was not given at generation time.  If C<$filename> begins
with C<http://> or C<ftp://>, the program C<wget> is used to download
the file.

The function C<language_dat_lines> returns the concatenation of all
files specified in C<BuildLanguageDat execute> directives in the present
TLPDB.  Exception: the result always begins with the contents of
C<language.us> file.  This and all the other files are looked for in
C<TLROOT/texmf/tex/generic/config>.

=head1 OPTIONS

Options regarding the full TeX Live installation to be described are saved
in a package C<00texlive.config> as values of C<depend> lines. This special
package C<00texlive.config> does not contain any files, only depend lines
which set one or more of the following options:

=over 6

=item C<container_split_src_files>

=item C<container_split_doc_files>

These options specify that at container generation time the source and
documentation files for a package have been put into a separate container
named C<package.source.extension> and C<package.doc.extension>.

=item C<container_format/I<format>>

This option specifies a format for containers. The currently supported 
formats are C<lzma> and C<zip>. But note that C<zip> is untested.

=back

To set these options the respective lines should be added to
C<00texlive.config.tlpsrc>.
