+Register an existing repository in a mrconfig file. By default, the
repository in the current directory is registered, or you can specify a
directory to register.
-By default it registers it to the ~/.mrconfig file. To make it write to a
-different file, use the -c option.
+The mrconfig file that is modified is chosen by either the -c option, or by
+looking for the closest known one at or below the current directory.

+Adds, modifies, removes, or prints a value from a mrconfig file. The next
parameter is the name of the section the value is in. To add or modify
values, use one or more instances of "parameter=value". Use "parameter=" to
remove a parameter. Use just "parameter" to get the value of a parameter.

=item help
Displays this help.
=item -c mrconfig

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

+given action. mr contains default handlers for "update", "status",
+"commit", and other standard actions. Normally you only need to specify what
+to do for "checkout".
Note that these shell commands are run in a "set -e" shell
environment, where any additional parameters you pass are available in
"$@". The "checkout" command is run in the parent of the repository
directory, since the repository isn't checked out yet. All other commands
are run inside the repository, though not necessarily at the top of it.

+repository. The "MR_CONFIG" environment variable is set to the .mrconfig file
+that defines the repo being acted on, or, if the repo is not yet in a config
+file, the .mrconfig file that should be modified to register the repo.
A few parameters have special meanings:
=item skip
-If the "skip" parameter is set and its command returns nonzero, then B<mr>
+If the "skip" parameter is set and its command returns true, then B<mr>
will skip acting on that repository. The command is passed the action
name in $1.
=item chain
-If the "chain" parameter is set and its command returns nonzero, then B<mr>
+If the "chain" parameter is set and its command returns true, then B<mr>
will try to load a .mrconfig file from the root of the repository. (You
should avoid chaining from repositories with untrusted committers.)
-=item deleted
-
-If the "deleted" parameter is set and its command returns nonzero, then
-B<mr> will treat the repository as deleted. It won't ever actually delete
-the repository, but it will warn if it sees the repository's directory.
-This is useful when one mrconfig file is shared amoung multiple machines,
-to keep track of and remember to delete old repositories.

=item lib
The "lib" parameter can specify some shell code that will be run before each
