Perl pod documentation

This translation of the Perl documentation (http://perldoc.perl.org) from POD to Texinfo is not official, and not endorsed by the Perl developers (indeed, they haven’t seen it). It was created by the GNU Texinfo developers because they found it useful to have the Perl documentation available in Info and other formats, and thought they would share the results. Suggestions welcome.

This is created entirely by the Texinfo tools; see the contrib/perldoc-all directory in the Texinfo sources for the procedure used. The output is available at http://www.gnu.org/software/perl/manual.
