    33 

    34 state: in progress

    35 

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

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

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

    39 A>``.

    40 

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

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

    43 relation versions changesets.
