+bzr, darcs and fossil repositories, and support for other revision
+control systems can easily be added.
B<mr> cds into and operates on all registered repositories at or below your
working directory. Or, if you are in a subdirectory of a repository that
contains no other registered repositories, it will stay in that directory,
and work on only that repository,
+B<mr> is configured by .mrconfig files, which list the repositories. It
+starts by reading the .mrconfig file in your home directory, and this can
+in turn chain load .mrconfig files from repositories. It also automatically
+looks for a .mrconfig file in the current directory, or in one of its
+parent directories.

These predefined commands should be fairly familiar to users of any revision
control system:

Interactive mode. If a repository fails to be processed, a subshell will be
started which you can use to resolve or investigate the problem. Exit the

If no number if specified, just operate on the repository for the current

Run the specified number of jobs in parallel, or an unlimited number of jobs
with no number specified. This can greatly speed up operations such as updates.

a good speedup in updates without loading the machine too much.

-B<mr> is configured by .mrconfig files. It starts by reading the .mrconfig
-file in your home directory, and this can in turn chain load .mrconfig files
-from repositories.
+=head1 MRCONFIG FILES
Here is an example .mrconfig file:
[src]
- checkout = svn co svn://svn.example.com/src/trunk src
+ checkout = svn checkout svn://svn.example.com/src/trunk src
chain = true
[src/linux-2.6]
Within a section, each parameter defines a shell command to run to handle a
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".
+"commit", and other standard actions.
+
+Normally you only need to specify what to do for "checkout". Here you
+specify the command to run in order to create a checkout of the repository.
+The command will be run in the parent directory, and must create the
+repository's directory. So use "git clone", "svn checkout", "bzr branch"
+or "bzr checkout" (for a bound branch), etc.
Note that these shell commands are run in a "set -e" shell
environment, where any additional parameters you pass are available in
-"$@". The "checkout" command is run in the parent of the repository
-directory, since the repository isn't checked out yet. All other commands
-are run inside the repository, though not necessarily at the top of it.
+"$@". All commands other than "checkout" 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. (For the "register" action, "MR_REPO" is instead set to the
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.
+The "MR_ACTION" environment variable is set to the command being run
+(update, checkout, etc).
+
A few parameters have special meanings:
=over 4
(included in mr's built-in library) to skip updating the repo unless it's
been at least 12 hours since the last update.
+ [mystuff]
+ checkout = ...
skip = test `whoami` != joey
+
+ [linux]
+ checkout = ...
skip = [ "$1" = update ] && ! hours_since "$1" 12
+
+Another way to use skip is for a lazy checkout. This makes mr skip
+operating on a repo unless it already exists. To enable the
+repo, you have to explicitly check it out (using "mr -d foo checkout").
+
+ [foo]
+ checkout = ...
+ skip = lazy
=item order
=item chain
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.)
+will try to load a .mrconfig file from the root of the repository.
=item include
Unlike all other parameters, this parameter does not need to be placed
within a section.
+B<mr> ships several libraries that can be included to add support for
+additional version control type things (unison, git-svn, vcsh, git-fake-bare,
+git-subtree). To include them all, you could use:
+
+ include = cat /usr/share/mr/*
+
+See the individual files for details.
+
+=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.
+
=item lib
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.
+=item fixups
+
+If the "fixups" parameter is set, its command is run whenever a repository
+is checked out, or updated. This provides an easy way to do things
+like permissions fixups, or other tweaks to the repository content,
+whenever the repository is changed.
+
+=item pre_ and post_
+
+If a "pre_action" parameter is set, its command is run before mr performs the
+specified action. Similarly, "post_action" parameters are run after mr
+successfully performs the specified action. For example, "pre_commit" is
+run before committing; "post_update" is run after updating.
+
=back
When looking for a command to run for a given action, mr first looks for
override these rcs specific actions. To add a new revision control system,
you can just add rcs specific actions for it.
+=head1 UNTRUSTED MRCONFIG FILES
+
+Since mrconfig files can contain arbitrary shell commands, they can do
+anything. This flexibility is good, but it also allows a malicious mrconfig
+file to delete your whole home directory. Such a file might be contained
+inside a repository that your main ~/.mrconfig checks out. To
+avoid worries about evil commands in a mrconfig file, mr defaults to
+reading all mrconfig files other than the main ~/.mrconfig in untrusted
+mode. In untrusted mode, mrconfig files are limited to running only known
+safe commands (like "git clone") in a carefully checked manner.
+
+To configure mr to trust other mrconfig files, list them in ~/.mrtrust.
+One mrconfig file should be listed per line. Either the full pathname
+should be listed, or the pathname can start with "~/" to specify a file
+relative to your home directory.
+
+=head1 OFFLINE LOG FILE
+
The ~/.mrlog file contains commands that mr has remembered to run later,
due to being offline. You can delete or edit this file to remove commands,
or even to add other commands for 'mr online' to run. If the file is
files providing such extensions are available in /usr/share/mr/. See
the documentation in the files for details about using them.
+=head1 EXIT STATUS
+
+mr returns nonzero if a command failed in any of the repositories.
