Tagging script for notmuch mail
The basic task of afew is to provide automatic tagging each time new mail is registered with notmuch. In a classic setup, you might call it after 'notmuch new' in an offlineimap post sync hook. . In addition to more elementary features such as adding tags based on email headers or maildir folders, handling killed threads and spam, it can do some heavy magic in order to /learn/ how to initially tag your mails based on their content. . In move mode, afew will move mails between maildir folders according to configurable rules that can contain arbitrary notmuch queries to match against any searchable attributes.
