lister for bitbucket repositories
We need a way to list all repositories hosted at bitbucket. For each of them we want to know its type (git/hg) and the URL we can clone/pull from.
Ideally, the lister should have two modes of operations, one to do a "full" listing that will list all repos available at the current time; and another "incremental" listing that only lists the new repos that have been created since the last (given) time.
