get_enclosures.pl
Normally I'm pretty spastic about releasing unpolished code. I tend to want to hang onto it until I'm proud enough of it to let it out in the wild. I'm making an exception for this thing, my Perl equivalent of Adam Curry's iPodder AppleScript. You should only download this if you are comfortable running Perl from the command line. If you don't know what that means, this is not for you I am afraid. For those who can handle that, and who don't have a problem installing CPAN modules, I present my script get_enclosures.pl.
Read the beginning comments inside that script to get the basics of how to use this. I include a paste of the crontab entry I use to automate this thing firing off twice a day. Anyone can take this and do anything with this. I only ask that if you improve it, please send me a copy of your changes so that I too can benefit from your expertise. As I say, I'm not being a control freak perfectionist and waiting until it is perfect to let it ride. We're all sharing first drafts here, so keep that perspective in mind as you look at it (ie, don't judge me harshly by this - this is a unique situation and not indicative of my standard work product.)
Update: As Adam pointed out, the download was boned. I had to zip it up, otherwise my web server was trying to execute the file rather than just serve it out as text. Whoops. Since I'm zipping it up now anyway, I went ahead and included my feeds.txt in there as well.
Update #2: For all of you coming from Adam's site or anyone that has downloaded this previously, see this post about how to subscribe to the get_enclosure specific feed to keep up with developments (no pun intended.) 0.1 is now available.
