Digtwit : Digmia Retweeter
Digtwit is a very simple command-line tool in Java, that checks for a hashtag (#digmia in our case) in a user's friends feed on Twitter and retweets any messages mentioning that hashtag automatically. By following a user, you allow a user to be included in automatic retweets. It is meant to be run from cron. For more, check doc/readme.txt in distribution (includes source code and binary).
And do not forget to follow digmia user on Twitter .
