WARNING: this tool is very incomplete and barely tested.  It is currently intended for active developers only.

hg-fastimport is (or will be) a tool which converts "git-fast-import" files into Mercurial repositories.  "git-fast-import" is a file format for representing the entire history of a version control repository.

http://www.kernel.org/pub/software/scm/git-core/docs/git-fast-import.html

This file format was designed to make it easier to write tools which converted from foreign VCS repository formats into "git" format; such tools exist for CVS, Mercurial, and Darcs.

http://repo.or.cz/w/fast-export.git
http://repo.or.cz/w/darcs2git.git

As well as the original "git-fast-import" program which imports these files into Git, a reader that imports them into Mercurial has been written

http://bazaar-vcs.org/BzrFastImport

With the addition of this tool, "git-fast-import" is becoming a "lingua franca" for the exchange of repository histories between revision control tools.

This tool draws heavily on the work done for BzrFastImport, and so is covered by the GPL.
