....thanks to the nice folks at http://www.koders.com/.
For example, if you go the to RMagick SCM page here:
http://rubyforge.org/scm/?group_id=12
there's a little textbox into which you can type "jpg" or whatever, and
then when you click "go" it'll open a new browser window to the koders
site with the search results. Like this:

Good times,
Yours,
Tom
