Well this was originally written as a utility to easily unfollow all the accounts you follow on Twitter. Unfortunately I didn't take the time to read Twitter's policy on automation rules.
Automated following/unfollowing: You may not follow or unfollow Twitter accounts in a bulk, aggressive, or indiscriminate manner. Aggressive following is a violation of the Twitter Rules. Please also review our following rules and best practices to ensure you are in compliance. Note that applications that claim to get users more followers are also prohibited under the Twitter Rules.
Turns out that after about 100 POST requests the API will revoke your access token.
Twitter however is kind enough to allow you to request the IDs of the accounts you follow in batches of 5000. This is limited to 15 requests within 15 minutes giving you the ability to fetch 75,000 IDs within each window.
If for some reason you want a snapshot (list of IDs) of the accounts you follow then this utility can at least handle that.
Usage of freebird:

Print all friend's IDs to stdout
-token string

-tokenSecret string

-unfollow

-username string
