+Hgpatch reads a patch, which should have been generated by
+a version control system like CVS, GIT, Mercurial, or Subversion,
+from a file (or standard input) and applies that patch to the local
+Mercurial repository.  If successful, it writes a list of affected
+files to standard output.
+
+Hgpatch is meant to be used by the Mercurial codereview extension.
+
+Usage:
+	hgpatch [patchfile]
