+"""Reduce the changesets evolution feature scope for early and noob friendly UI
+
+The full scale changeset evolution have some massive bleeding edge and it is
+very easy for people not very intimate with the concept to end up in intricate
+situation. In order to get some of the benefit sooner, this extension is
+disabling some of the less polished aspect of evolution. It should gradually
+get thinner and thinner as changeset evolution will get more polished. This
+extension is only recommended for large scale organisations. Individual user
+should probably stick on using Evolution in its current state, understand its
+concept and provide feedback
+
+The first feature provided by this extension is the ability to "inhibit"
+obsolescence markers. Obsolete revision can be cheaply brought back to life
+that way. However as the inhibitor are not fitting in an append only model,
+this is incompatible with sharing mutable history.
+
+The second feature is called direct access. It is the ability to refer and
+access hidden sha in commands provided that you know their value.
+For example hg log -r XXX where XXX is a commit has should work whether XXX is
+hidden or not as we assume that the user knows what he is doing when referring
+to XXX.
