For the record, the very first cross-project merge is: http://thread.gmane.org/gmane.comp.version-control.git/5126 The procedure to maintain the resulting re-merge of two histories do not involve subtree merge because "The coolest merge ever" merges non-overlapping two trees at the same level, but the principle used to bootstrap the process is the same. You prepare a tree that is a overlay of the tips of your two projects, and record that tree in a commit that is a merge between two parents. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
