+    Push changesets from the local repository to the specified
+    destination.
+
+    This operation is symmetrical to pull: it is identical to a pull
+    in the destination repository from the current one.
+
+    By default, push will not allow creation of new heads at the
+    destination, since multiple heads would make it unclear which head
+    to use. In this situation, it is recommended to pull and merge
+    before pushing.
+
+    Use -f/--force to override the default behavior and push all
+    changesets on all branches.
+
+    If -r/--rev is used, the specified revision and all its ancestors
+    will be pushed to the remote repository.
