Updated version of the instructions in http://traviscline.com/blog/2010/04/27/using-hg-git-to-work-in-git-and-push-to-hg/ with a few tweaks

#. Install hg-git (e.g. ``pip install hg-git``)

#. Make sure you've enabled the Hg bookmark extension in your ``.hgrc``

#. Add this to your .hgrc::

    [git]
    intree=1
    [extensions]
    hggit =

And also .hg/hgignore: http://mercurial.selenic.com/wiki/TipsAndTricks#Ignore_files_in_local_working_copy_only

#. Clone your Mercurial repo::

    $ hg clone https://acdha@bitbucket.org/ned/coveragepy

#. Change into the repo::

    $ cd coveragepy

#. Create a local bookmark tracking your Mercurial default branch - this is
   what will be exported to Git::
   
    $ hg bookmark hg/default -r default

#. Export to the git repo::

    $ hg gexport

#. Configure Hg to ignore the Git repo::

    $ echo ".git" >> .hg/hgignore

#. Configure Git to ignore the Hg repo::

    $ echo ".hg*" >> .git/info/exclude

#. Configure Git to ignore the same things as Mercurial::

    $ git config core.excludesfile `pwd`/.hg/hgignore

#. Have your master branch track the exported Hg default branch::

    $ git branch --track hg/default master
    $ git reset --hard

#. hg-git created a "bare" git repository, even with intree = 1. Change that in .git/config, replace bare = true by bare = false.

#. Do stuff in Git and make commits

#. Export your changes to Hg::

    $ hg gimport
    
#. Push them out to the world::

    $ hg push
