Kilon,
You can use an expression like the following to load projects directly from github using Metacello 1.0.0-beta.32.16:
�� Metacello new
������ baseline: 'BaselineOfXXX';
������ repository: 'github://<user name>/<project name>[:comitish]/<path to filetree repo>'
������ get;
������ load.
there are some examples of Seaside load expressions here[1]. Whenever you use the `get` command, the github repo is refreshed from github. The `load` loads directly from the local github cache for the project.
