Then if you want to get the last released version, you can do:

pip install mu-repo

If you want to grab from Github directly (which may be even better if you have multiple Python installs around), you can clone it from the path:

git clone git://

and then add the mu-repo directory to your PATH, that way, executing mu in the command line should give a proper message.

Note: if you installed from Github, mu auto-update can be used to grab the latest changes (if you used pip, use pip itself to upgrade mu-repo).
