B<mr> is configured by .mrconfig files. It starts by reading the .mrconfig
-file in your home directory. Each repository specified in a .mrconfig file
-can also have its own .mrconfig file in its root directory that can
-optionally be used as well. So you could have a ~/.mrconfig that registers a
-repository ~/src, that itself contains a ~/src/.mrconfig file, that in turn
-registers several additional repositories.
+file in your home directory, and this can in turn chain load .mrconfig files
+from repositories.
+
+Here is an example .mrconfig file:
+
+ [src]
+ checkout = svn co svn://svn.example.com/src/trunk src
+ chain = true
+
+ [src/linux-2.6]
+ checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
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.
-The "default" section allows setting default values for the sections that
+The "DEFAULT" section allows setting default values for the sections that
come after it.
-The "alias" section allows adding aliases for actions. Each parameter
+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
The "MR_REPO" environment variable is set to the path to the top of the
repository.
-There are three special parameters. If the "skip" parameter is set and
-its command returns nonzero, then B<mr> will skip acting on that repository.
+A few parameters have special meanings:
+
+=over 4
+
+=item skip
+
+If the "skip" parameter is set and its command returns nonzero, then B<mr>
+will skip acting on that repository.
+
+=item chain
+
If the "chain" parameter is set and its command returns nonzero, 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.) 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 for other commands
-to use.
