Avery (cc-ed) has written a\nprogram 'git subtree' that lets you split off subtrees from a git\nrepository (and optionally merge them back later on). I reckon that's\nwhat you want, yes?\n\n-- \nCheers,\n\nSverre Rabbelier\n"},{"id":"136047","messageId":"fabb9a1e1003021519y7159a3dal3aa3a7514329fb9a@mail.gmail.com","threadId":"22874","inReplyTo":"20100303002132.5df20326@gmail.com","subject":"Re: split up a repository","fromName":"Sverre Rabbelier","fromEmail":"srabbelier@gmail.com","sentAt":"2010-03-02T23:19:48Z","receivedAt":"2010-03-02T23:19:48Z","isPatch":false,"sender":{"key":"srabbelier@gmail.com","avatar":"https://avatars.githubusercontent.com/u/3098?v=4"},"body":"Heya,\n\nOn Wed, Mar 3, 2010 at 00:21, Levente Kovacs wrote:\n> Ok.

Personally, I add the git-subtree\nsource directory to my PATH from .bashrc... but I guess I'm special\nbecause I also change my version of git-subtree a lot :)\n\nMake sure to run 'make test' first so you know it's working on your computer.\n\nAnd I'll second Sverre's suggestion to *always* back up your\nrepository before doing weird stuff (although git-subtree is designed\nto refuse to overwrite existing branches, and nobody has ever reported\nit damaging anything).\n\nHave fun,\n\nAvery\n"},{"id":"136077","messageId":"19342.27760.544227.835077@blake.zopyra.com","threadId":"22874","inReplyTo":"32541b131003021740n32535fbbh802af418ea0898aa@mail.gmail.com","subject":"Re: split up a repository","fromName":"Bill Lear","fromEmail":"rael@zopyra.com","sentAt":"2010-03-03T14:04:32Z","receivedAt":"2010-03-03T14:04:32Z","isPatch":false,"sender":{"key":"rael@zopyra.com","avatar":"https://gravatar.com/avatar/c4f2d2790ca3828d3b4e7dfebabf61d2fe94fd82fa49cdac2a5295dd2d46a874?d=mp&s=160"},"body":"On Tuesday, March 2, 2010 at 20:40:57 (-0500) Avery Pennarun writes:\n>On Tue, Mar 2, 2010 at 6:21 PM, Levente Kovacs wrote:\n>> On Tue, 2 Mar 2010 11:40:41 +0100\n>> Ok.
