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

+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.

Note that these shell commands are run in a "set -e" shell
environment, where any additional parameters you pass are available in
are run inside the repository, though not necessarily at the top of it.
The "MR_REPO" environment variable is set to the path to the top of the
-repository, and "MR_CONFIG" 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

A few parameters have special meanings:

should avoid chaining from repositories with untrusted committers.)
-=item deleted
-
-If the "deleted" parameter is set and its command returns true, 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.
