B<mr> [options] register [repository]
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
-repository. It supports any combination of subversion, git, cvs, mecurial,
+repository. It supports any combination of subversion, git, cvs, mercurial,
bzr and darcs repositories, and support for other revision control systems can
easily be added.

-=item bootstrap url
+=item bootstrap url [directory]
-Causes mr to download the url, save it to a .mrconfig file in the
-current directory, and then check out all repositories listed in it.
+Causes mr to download the url, and use it as a .mrconfig file
+to checkout the repositories listed in it, into the specified directory.
+
+The directory will be created if it does not exist. If no directory is
+specified, the current directory will be used.
+
+If the .mrconfig file includes a repository named ".", that
+is checked out into the top of the specified directory.
=item list (or ls)
=item -d directory
+=item --directory directory
+
Specifies the topmost directory that B<mr> should work in. The default is
the current working directory.
=item -c mrconfig
+=item --config mrconfig
+
Use the specified mrconfig file. The default is B<~/.mrconfig>
=item -p
+=item --path
+
Search in the current directory, and its parent directories and use
the first B<.mrconfig> found, instead of the default B<~/.mrconfig>.
=item -v
+=item --verbose
+
Be verbose.
=item -q
+=item --quiet
+
Be quiet.
+=item -k
+
+=item --insecure
+
+Accept untrusted SSL certificates when bootstrapping.
+
=item -s
+=item --stats
+
Expand the statistics line displayed at the end to include information
about exactly which repositories failed and were skipped, if any.
=item -i
+=item --interactive
+
Interactive mode. If a repository fails to be processed, a subshell will be
started which you can use to resolve or investigate the problem. Exit the
subshell to continue the mr run.
=item -n [number]
+=item --no-recurse [number]
+
If no number if specified, just operate on the repository for the current
directory, do not recurse into deeper repositories.
=item -j [number]
+=item --jobs [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.
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.
+=item -t
+
+=item --trust-all
+
+Trust all mrconfig files even if they are not listed in ~/.mrtrust.
+Use with caution.

present, mr assumes it is in offline mode.

+=head1 "UNTRUSTED MRCONFIG FILES"
Since mrconfig files can contain arbitrary shell commands, they can do
anything. This flexability is good, but it also allows a malicious mrconfig
file to delete your whole home directory. Such a file might be contained
-inside a repository that your main ~/.mrconfig checks out. To avoid worries
-about a malicious change being committed to such a file, mr has the ability
-to read mrconfig files in untrusted mode. Such files are limited to running
-only known safe commands (like "git clone").
+inside a repository that your main ~/.mrconfig checks out and chains to. To
+avoid worries about evil commands in a mrconfig file, mr
+has the ability to read mrconfig files in untrusted mode. Such files are
+limited to running only known safe commands (like "git clone") in a
+carefully checked manner.
By default, mr trusts all mrconfig files. (This default will change in a
future release!) But if you have a ~/.mrtrust file, mr will only trust
