+  
+      Commits a new changeset incorporating both the changes to the given files
+      and all the changes from the current parent changeset into the repository.
+  
+      See "hg commit" for details about committing changes.
+  
+      If you don't specify -m, the parent's message will be reused.
+  
+      Behind the scenes, Mercurial first commits the update as a regular child
+      of the current parent. Then it creates a new commit on the parent's
+      parents with the updated contents. Then it changes the working copy parent
+      to this new combined changeset. Finally, the old changeset and its update
+      are hidden from "hg log" (unless you use --hidden with log).
+  
+      Returns 0 on success, 1 if nothing changed.
