Mutable History For Mercurial

=============================

This repository holds three experimental extensions that introduce concepts

related to history rewriting in mercurial.

:states:

    Introduce a state concept. It allows to track which changesets have been

    made public and immutable and which you want to keep local.

:obsolete:

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

    changesets.

:rewrite:

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

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

Obsolete Extension

======================

state: in progress

This extension introduces the *obsolete* concept. It adds a new *obsolete*

relation between two changesets. A relation ``<changeset B> obsolete <changeset

A>`` is set to denote that ``<changeset B>`` is new version of ``<changeset

A>``.

The *obsolete* relation act as a **perpendicular history** to the standard

changeset history. Standard changeset history versions files. The *obsolete*

relation versions changesets.

Usage and Feature
