+Split patch in MQ.
+==================
+
+Enable built-in extensions::
+
+  [extensions]
+  mq=
+  record=
+  shelve=
+
+Then move MQ into working tree and split changes and remove original patch::
+
+  $ hg qpop my.patch
+  $ patch -p1 <.hg/patches/my.patch
+
+  $ hg qnew -i my1.patch
+   ....
+  $ hg qnew -i my2.patch
+   ....
+  $ hg qnew myN.patch   # last without interactive stuff
+
+  $ hg qdelete --keep my.patch
+
+Between ``my$i.patch`` and ``my$((i+1)).patch`` you can use ``hg shelve``/``hg
+unshelve`` to test if project built and pass tests on top of ``my$i.patch``
+without later changes!
+
+If you find that something missing on this stage use ``hg qref`` on shelved
+changes or ``hg qref -i`` on unshelved changes!
+
