=head1 DESCRIPTION

Return all the files contained in the given TeX Live package (as
determined by reading the TeX Live package database).  This includes
any executables as well as runtime, documentation, and source files.

It does not include the C<.tlpsrc> file for the package, since that is
necessarily part of the build infrastructure rather than the
self-contained package.

=head1 AUTHORS AND COPYRIGHT

This script and its documentation were written for the TeX Live
distribution (L<http://tug.org/texlive>) and both are licensed under the
GNU General Public License Version 2 or later.
