=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>.
