Git-cinnabar is a git remote helper to interact with mercurial
repositories. It allows to clone, pull and push from/to mercurial remote
repositories, using git.

What's new since 0.1.1?

- git cinnabar git2hg and git cinnabar hg2git commands that allow to
  translate (possibly abbreviated) git sha1s to mercurial sha1s and
  vice-versa.
- A "native" helper that makes some operations faster. It is not
  required for git-cinnabar to work, but it can improve performance
  significantly. Check the Setup instructions in the README file.
- Do not store mercurial metadata when pushing to non-publishing
  repositories.
- Made the discovery phase of pushes require less round trips (the phase
  that finds what is common between the local and remote repositories),
  hopefully making pushing faster.
- Improved logging, which now doesn’t require fiddling with the code to
  get extra logging.
- Made fsck validate more things, and act on more errors.
- Fixed a few edge cases.
- Better handle files with weird names, and that git quotes in its
  output.
- Extensively tested on the following repositories:
    https://hg.mozilla.org/mozilla-central/
    https://hg.mozilla.org/releases/mozilla-beta/
    https://selenic.com/hg/
    https://bitbucket.org/durin42/hg-git/
    https://hg.python.org/cpython/

What to expect next?

- Allow to push merge commits.
- Improve memory footprint for pushes (currently, it’s fairly
  catastrophic on big repositories ; don’t try to push multiple hundreds
  of commits of a Mozilla-sized repository if you don’t have multiple
  gigabytes of memory available).
- As mentioned above, allow to remove some metadata.
- And more...

If you want to follow the improvements more closely, I encourage you to
switch to the `next` branch. I won’t push anything there that hasn’t
been extensively tested on the above mentioned repositories.

And as always, please report any issue you run into:
