-hg-to-git.py is able to convert a Mercurial repository into a git one,
-and preserves the branches in the process (unlike tailor)
-
-hg-to-git.py can probably be greatly improved (it's a rather crude
-combination of shell and python) but it does already work quite well for
-me. Features:
-       - supports incremental conversion
-         (for keeping a git repo in sync with a hg one)
-        - supports hg branches
-        - converts hg tags
-
-Note that the git repository will be created 'in place' (at the same
-location as the source hg repo). You will have to manually remove the
-'.hg' directory after the conversion.
-
-Also note that the incremental conversion uses 'simple' hg changesets
-identifiers (ordinals, as opposed to SHA-1 ids), and since these ids
-are not stable across different repositories the hg-to-git.py state file
-is forever tied to one hg repository.
