=head1 NAME
|
|
|
|
pl2pm - Rough tool to translate Perl4 .pl files to Perl5 .pm modules.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<pl2pm> F<files>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<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.
|
|
|
|
=head1 LIMITATIONS
|
|
|
|
It's just a first step, but it's usually a good first step.
