mr - a Multiple Repository management tool
=head1 SYNOPSIS
-/
+
B<mr> [options] checkout
B<mr> [options] update
The optional -m parameter allows specifying a commit message.
+=item push
+
+Pushes committed local changes to the remote repository. A no-op for
+centralized revision control systems.
+
=item diff
Show a diff of uncommitted changes.
It is not recommended for interactive operations.
Note that running more than 10 jobs at a time is likely to run afoul of
-ssh connection limits. Running between 3 and 5 jobs at a time will yeild
+ssh connection limits. Running between 3 and 5 jobs at a time will yield
a good speedup in updates without loading the machine too much.
