=============================
Mutable History For Mercurial
=============================

:obsolete:

    Introduce an ``obsolete`` concept that tracks new versions of rewritten
    changesets.

:evolve:

    A collection of commands to rewrite the mutable part of the history.



**These extensions are experimental and are not meant for production.**

You can quicky enable them using::

    ./enable.sh >> ~/.hgrc

But it's recommended to look at the doc in the first place.

See doc/ directory for details.

Online version of the doc is available:

    http://hg-lab.logilab.org/doc/mutable-history/html/

Contribute
==================

The simplest way to contribute is to issue a pull request on bitbucket.

However, some cutting edge change may be found in a mutable repository hosted
by logilab before they are published.

    http://hg-lab.logilab.org/wip/mutable-history/

Make sure to check lastest draft changeset before submitting new changeset.
