 This is the source code to my personal IMAP-based mail filtering tool. I use it every day, and it has proven to be useful for me. You are more than welcome to use and contribute to it.

 You must create a `rules` configuration file which tells `gmailfilter` how to connect to your IMAP mail server, and what to do with all the mail in your inbox. The approach `gmailfilter` takes to mail filtering is that your inbox should be virtually empty at the end of a filter run - only messages which need "active processing" should remain (usually this means "unread and flagged (starred) messages"). `gmailfilter` takes care of iterating over the messages in your inbox, and will run your rules over any new messages that arrive.
