A script that pulls down RSS/Atom feeds and sends you email. All text is forced to text/plain with 7-bit ASCII.
The list of feeds to read is kept in a flat text file, which you can easily curate with emacs/vim/whatever. The list of posts you've already gotten emails about are kept in a sqlite database, which you can manipulate with the sqlite3 command line tool. There is an option which lets you remove old posts to keep the db size down if this seems necessary.
Requires Universal Feed Parser and stripogram, with optional use of dateutil and multiprocessing.
This works very well with the feeds I happen to read, but may not work for you.
Todo: Use BeautifulSoup instead of stripogram, extract all links and use "lynx -dump"-style formatting.
Current release grab_rss 0.2 (2010-03-25)
