Well we support fast-import so you can get your history into BK and play trivially. BK does more and less than git/hg. It's got richer history, it was trivial to write a bk fast-export that git could import. Writing a bk fast-import wasn't so bad but an incremental one is hard because git doesn't store as much history (no per file history, actually no file object, just pathnames that have some data, not the same, we have a DAG per file, makes history better, makes merges faster and easier). Mercurial copied our UI so for a lot of stuff if you know hg <cmd> then bk <cmd> will just work. BK predates all these systems, they picked up some of bk's commands. There is a cheatsheet (somewhat out of date but it will get you going) at: http://mcvoy.com/lm/bkdocs/bk_refcard.pdf http://mcvoy.com/lm/bkdocs/bk_refcard.pdf And you can email dev <at> bitkeeper.com or hit up http://bitkeeper.org http://bitkeeper.org for more info.
