+
+    This command can be used to restore stacks of changesets to an obsolete
+    state, creating identical identical copies.
+
+    There are two mains way to select the rewind target. Rewinding "from"
+    changesets will restore the direct precursors of theses changesets (and
+    obsolete the changeset you rewind from). Rewinding "to" will restore the
+    changeset you have selected (and obsolete their latest successors).
+
+    By default, we rewind from the working copy parents, restoring its
+    precursor.
+
+    When we rewind to an obsolete version, we also rewind to all its obsolete
+    ancestors. To only rewind to the explicitly selection changesets use the
+    `--exact` flag. Using the `--exact` flag can restore some changesets as
+    orphan.
+
+    The latest successors the obsolete changesets will be superseed by these
+    new copies. This behavior can be disabled using `--as-divergence`, the
+    current latest successors won't be affected and content-divergence will
+    appears between them and the restored version of the obsolete changesets.
+
+    Current rought edges:
+
+      * fold: rewinding to only some of the initially folded changesets will be
+              problematic. The fold result is marked obsolete and the part not
+              rewinded too are "lost".  Please use --as-divergence when you
+              need to perform such operation.
+
+      * :hg:`rewind` might affect changeset outside the current stack. Without --exact, we
+              also restore ancestors of the rewind target, obsoleting their
+              latest successors (unless --as-divergent is provided). In some
+              case, these latest successors will be on branches unrelated to
+              the changeset you rewind from.

+Tests for the --abort flag for `hg evolve` command while content-divergence resolution
+======================================================================================
+
+The `--abort` flag aborts the interuppted evolve by undoing all the work which
+was done during resolution i.e. stripping new changesets created, moving
+bookmarks back, moving working directory back.

+Testing the `--no-update` flag to `hg evolve` command
+=====================================================
+
+There is an `--update` flag to `hg evolve` command which defaults to True. The
+`--update` flag updates to the head of the evolved revisions. If you dont want
+to change your working directory or update your working directory to its
+sucessor after hg evolve, `hg evolve --no-update` is the thing for you.
+
+This patch tests that flag.
