"""hide changesets by marking them obsolete
Pruned changesets are obsolete with no successors. If they also have no
descendants, they are hidden (invisible to all commands).
Non-obsolete descendants of pruned changesets become "unstable". Use
:hg:`evolve` to handle this situation.
When you prune the parent of your working copy, Mercurial updates the
working copy to a non-obsolete parent.
You can use ``--succ`` to tell Mercurial that a newer version (successor)
of the pruned changeset exists. Mercurial records successor revisions in
obsolescence markers.
You can use the ``--biject`` option to specify a 1-1 mapping (bijection)
between revisions to pruned (precursor) and successor changesets. This
option may be removed in a future release (with the functionality provided
automatically).
If you specify multiple revisions in ``--succ``, you are recording a
"split" and must acknowledge it by passing ``--split``. Similarly, when you
prune multiple changesets with a single successor, you must pass the
``--fold`` option.
