Convert perl scripts to python with the awesome power of regular expressions.

=head1 NAME

pl2py.pl

=head1 DESCRIPTION

Attempts to convert perl scripts to python with the awesome power of regular expressions.

=head1 BUGS

This will (probably) not actually produce runnable python files. But it saves a lot of work converting some perl to python.

More useful if your perl code is well-indented to start with (consider using a source formatter first).

What if I tried to convert this script to python... woah.
