pview is a perl source code viewer. It highlights the code using a pretty good Perl tokenizer.

The color scheme can be very easy customized inside the script.

On the same concept, a new script has been created, called 'scgrep' which grabs form a Perl script only the elements that the reader wants. (e.g.: regular expressions, operators, numbers, etc...)

Even better, this tools are now available as part of the Perl::Tokenizer CPAN module, which also include another interesting tool, called pl2html which highlights Perl code in HTML.
