B<mr> is a Multiple Repository management tool. It can checkout, update, or
perform other actions on a set of repositories as if they were one combined
-respository. It supports any combination of subversion, git, cvs, mecurial,
+repository. It supports any combination of subversion, git, cvs, mecurial,
bzr and darcs repositories, and support for other revision control systems can
easily be added.

-Actions can be abbreviated to any unambiguous subsctring, so

+Actions can be abbreviated to any unambiguous substring, so
+"mr st" is equivalent to "mr status", and "mr up" is equivalent to "mr

Additional parameters can be passed to most commands, and are passed on
Expand the statistics line displayed at the end to include information
about exactly which repositories failed and were skipped, if any.

-Just operate on the repository for the current directory, do not
-recurse into deeper repositories.
+If no number if specified, just operate on the repository for the current
+directory, do not recurse into deeper repositories.
-=item -j number
+If a number is specified, will recurse into repositories at most that many
+subdirectories deep. For example, with -n 2 it would recurse into ./src/foo,
+but not ./src/packages/bar.
-Run the specified number of jobs in parallel. This can greatly speed up
-operations such as updates. It is not recommended for interactive
-operations.
+=item -j [number]
+
+Run the specified number of jobs in parallel, or an unlimited number of jobs
+with no number specified. This can greatly speed up operations such as updates.
+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
+a good speedup in updates without loading the machine too much.
