Nothing git has currently will let you clone a subset of files. Shallow clones exist if you want all the code and the last X changes. The reason for this is git, like other DVCSes, tracks _changes_ rather than _files_ this is something that took me a while to get my head around when I was learning git. The best advice I've seen is to actually take your repository and use git filter-branch to create several smaller repositories (or depending on your desire for retention of history just create new repos). You can then use submodules or subtrees to stitch these back together into a super project to which you can add the smaller repositories as needed (note: I have never used subtrees so I'm not 100% sure if what I'm saying applies to them) . We use this model with submodules at $dayjob and it works quite well for us. -- 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
