To make changes or features in the source code, browse the repository at http://www.bitbucket.org/aafshar/glashammer-main/overview/ and click the fork button.
Once you are happy with the changes and code has been reviewed we can pull into the main branch.
If you hate Mercurial, then I am sorry, there are no longer any alternatives. If you would like to maintain a mirror for git or bzr or something, please let us know, and we shall happily list it here.
