=============================
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
    - issues several warning messages when troubles appear in your repository

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

You can quickly enable it by adding the line below to the extensions
section of your 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 changes 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 latest draft changeset before submitting new changesets.
