I see over the last year (on the web and in this mailing list) there was some activity to extend subtree with a .gittrees file and push-all/pull-all commands.
Perhaps I missed it, but looking through the latest git code on the github mirror I can't find any reference to the .gittrees file or these commands.
Does anyone know the status of this feature? Was it decided that this was a bad idea and the feature has been rejected? Or is this a feature still "cooking"...which will likely make it into git mainline at some point?
I ask because I would like to use something like this to be able to keep a combined repository and separate project repositories in sync. Of course, if it was decided that this feature is fundamentally a bad idea then I will do something different.
