Easily add a new Bitbucket repo on a Redmine server. Add this to the Redmine user's .bash_profile, run `bitbucket-add-repository <slug>`, then add the repo to Redmine project configuration. Modifying this to use with Github is trivial, just update git@bitbucket.org to git@github.com (and update textual references, of course).

# Before running this command ensure that the repo on Bitbucket has an appropriate deploy key.
# You'll also want to set a POST hook (e.g. http://{redmine}/github_hook?project_id={slug})

# Usage: bitbucket-add-repository <slug>
