No. Completely own BSD-licensed DVCS designed specifically for FreeBSD, allowing partial checkouts and intended to replace SVN in the future :) If you briefly know the git ot hg architecture, then you may notice that "commit" references "tree", each subdir points to another "tree", so that "tree" is like a directory on a FAT file system: file name directly references file data. So only entire repository could be fetched. If it will be designed like a Unix file systems, then an "inode" object could be separate from "directory", and with a little help partial checkouts are now possible (subset of inodes). Git also doesn't handle renames natively, and with inodes it should be a trivial change in the "directory" file, easily mergeable. -- WBR, Vadim Goncharov.
