=head1 DESCRIPTION
List the repositories that mr will act on.
+=item register
+
+Register an existing repository in the mrconfig file. By default, the
+epository in the current directory is registered, or you can specify a
+directory to register.
+
+=item config
+
+Adds, modifies, removes, or prints a value from the 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.
+
+For example, to add (or edit) a repository in src/foo:
+
+ mr config src/foo checkout="svn co svn://example.com/foo/trunk foo"
+
+To show the command that mr uses to update the repository in src/foo:
+
+ mr config src/foo update
+
=item help
Displays this help.
"mr st" is equivilant to "mr status", and "mr up" is equivilant to "mr
update"
-Additional parameters can be passed to other commands than "commit", they
-will be passed on unchanged to the underlying revision control system.
-This is mostly useful if the repositories mr will act on all use the same
-revision control system.
+Additional parameters can be passed to most commands, and are passed on
+unchanged to the underlying revision control system. This is mostly useful
+if the repositories mr will act on all use the same revision control
+system.

The .mrconfig file uses a variant of the INI file format. Lines starting with
-"#" are comments. Lines ending with "\" are continued on to the next line.
+"#" are comments. Values can be continued to the following line by
+indenting the line with whitespace.
The "DEFAULT" section allows setting default values for the sections that
come after it.
The "ALIAS" section allows adding aliases for actions. Each parameter
is an alias, and its value is the action to use.
-All other sections specify where each repository is located, relative to the
-directory that contains the .mrconfig file.
+All other sections add repositories. The section header specifies the
+directory where the repository is located. This is relative to the directory
+that contains the mrconfig file, but you can also choose to use absolute
+paths.
Within a section, each parameter defines a shell command to run to handle a
given action. mr contains default handlers for the "update", "status", and
=item skip
If the "skip" parameter is set and its command returns nonzero, then B<mr>
-will skip acting on that repository.
+will skip acting on that repository. The command is passed the action
+name in $1.
+
+Here are two examples. The first skips the repo unless
+mr is run by joey. The second uses the hours_since function
+(included in mr's built-in library) to skip updating the repo unless it's
+been at least 12 hours since the last update.
+
+ skip = test $(whoami) != joey
+ skip = [ "$1" = update ] && [ $(hours_since "$1") -lt 12 ]
=item chain
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 repsoitory'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
