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


Extends Mercurial feature related to Changeset Evolution

This extension provides several commands to mutate history and deal with
issues it may raise.

It also:

    - enables the "Changeset Obsolescence" feature of mercurial,
    - alters core commands and extensions that rewrite history to use
      this feature,
    - improves some aspect of the early implementation in 2.3

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

You can quicky enable it by adding the line below to the extensions
section of you hgrc::

    evolve=PATH/TO/evolve.py

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.

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