man pl2pm (Commandes) - Rough tool to translate Perl4 .pl files to Perl5 .pm modules.
NAME
pl2pm - Rough tool to translate Perl4 .pl files to Perl5 .pm modules.
SYNOPSIS
pl2pm files
DESCRIPTION
pl2pm is a tool to aid in the conversion of Perl4-style .pl library files to Perl5-style library modules. Usually, your old .pl file will still work fine and you should only use this tool if you plan to update your library to use some of the newer Perl 5 features, such as AutoLoading.
LIMITATIONS
It's just a first step, but it's usually a good first step.
