Testing Perl Support for Google SyntaxHighlighter

Note that this post is no longer formatted as it states below.

I've been enjoying playing with Google's SyntaxHighlighter. Another user came up with a Perl brush file, so I thought I'd give it a shot. One note from the author of the brush file is that -> gets converted to -> rather than being translated properly. It's definitely the highlighter that does it, too, because when you disable the brush it shows up properly.

About three years ago I was living in the shell. I had a script aliased to m that would run a perl script for each of my IMAP accounts and show me all of the unread messages. The script had been originally written by a fellow Help Desk supervisor at UB and then given colorization support by another fellow supervisor, Doug, who has since become a perl and python guru.

The trouble then was that, while this worked for my home email server, I had to change some of the socket code to work on all of the other IMAP servers I used. That wasn't too tough since IMAP is a relatively straightforward protocol. Getting POP support to work looked to be a lot harder, however. I couldn't find anyone that had written something similar for me to hack, so I wrote my own.

This script above uses the perl module Mail::Box which installs straight out of CPAN. It's probably been updated since this was written, and I don't even know if the script still works (who still uses POP??).
