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.
-Sections specify where each repository is located, relative to the
+
+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.
Within a section, each parameter defines a shell command to run to handle a
-given action. Note that these shell commands are run in a "set -e" shell
+given action. mr contains default handlers for the "update", "status", and
+"commit" actions, so 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
will try to load a .mrconfig file from the root of the repository. (You
should avoid chaining from repositories with untrusted committers.) The
"lib" parameter can specify some shell code that will be run before each
-command, this can be a useful way to define shell functions other commands
-can use.

-The "default" section allows setting up default handlers for each action,

-handlers for the "update", "status", and "commit" actions, so normally
