     The norepo argument defines whether the command does not require a
     local repository. Most commands operate against a repository, thus the
     default is False.
 
     The optionalrepo argument defines whether the command optionally requires
     a local repository.

+    The inferrepo argument defines whether to try to find a repository from the
+    command line arguments. If True, arguments will be examined for potential
+    repository locations. See ``findrepo()``. If a repository is found, it
