=head1 DESCRIPTION
B<mr> is a Multiple Repository management tool. It can checkout, update, or
perform other actions on a set of repositories as if they were one combined
-repository. It supports any combination of subversion, git, cvs, mecurial,
-bzr and darcs repositories, and support for other revision control systems can
-easily be added.
+repository. It supports any combination of subversion, git, cvs, mercurial,
+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:
The optional -m parameter allows specifying a commit message.
+=item push
+
+Pushes committed local changes to the remote repository. A no-op for
+centralized revision control systems.
+
=item diff
Show a diff of uncommitted changes.
Show the commit log.
+=item run command [param ...]
+
+Runs the specified command in each repository.
+

These commands are also available:
=over 4
+=item bootstrap url [directory]
+
+Causes mr to download the url, and use it as a .mrconfig file
+to checkout the repositories listed in it, into the specified directory.
+
+The directory will be created if it does not exist. If no directory is
+specified, the current directory will be used.
+
+If the .mrconfig file includes a repository named ".", that
+is checked out into the top of the specified directory.
+
=item list (or ls)
List the repositories that mr will act on.
directory to register.
The mrconfig file that is modified is chosen by either the -c option, or by
-looking for the closest known one at or below the current directory.
+looking for the closest known one at or in a parent of the current directory.
=item config
mr config DEFAULT lib
-The ~/.mrconfig file is used by default. To use a different config file,
-use the -c option.
+The mrconfig file that is used is chosen by either the -c option, or by
+looking for the closest known one at or in a parent of the current directory.
+
+=item offline
+
+Advises mr that it is in offline mode. Any commands that fail in
+offline mode will be remembered, and retried when mr is told it's online.
+
+=item online
+
+Advices mr that it is in online mode again. Commands that failed while in
+offline mode will be re-run.
+
+=item remember
+
+Remember a command, to be run later when mr re-enters online mode. This
+implicitly puts mr into offline mode. The command can be any regular mr
+command. This is useful when you know that a command will fail due to being
+offline, and so don't want to run it right now at all, but just remember
+to run it when you go back online.
=item help
=item -d directory
+=item --directory directory
+
Specifies the topmost directory that B<mr> should work in. The default is
the current working directory.
=item -c mrconfig
-Use the specified mrconfig file. The default is B<~/.mrconfig>
+=item --config mrconfig
+
+Use the specified mrconfig file. The default is to use both B<~/.mrconfig>
+as well as look for a .mrconfig file in the current directory, or in one
+of its parent directories.
=item -v
+=item --verbose
+
Be verbose.
=item -q
+=item --quiet
+
Be quiet.
+=item -k
+
+=item --insecure
+
+Accept untrusted SSL certificates when bootstrapping.
+
=item -s
+=item --stats
+
Expand the statistics line displayed at the end to include information
about exactly which repositories failed and were skipped, if any.
+=item -i
+
+=item --interactive
+
+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
+subshell to continue the mr run.
+
=item -n [number]
+=item --no-recurse [number]
+
If no number if specified, just operate on the repository for the current
directory, do not recurse into deeper repositories.
=item -j [number]
+=item --jobs [number]
+
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.
It is not recommended for interactive operations.
Note that running more than 10 jobs at a time is likely to run afoul of
-ssh connection limits. Running between 3 and 5 jobs at a time will yeild
+ssh connection limits. Running between 3 and 5 jobs at a time will yield
a good speedup in updates without loading the machine too much.

+=item -t
+
+=item --trust-all
+
+Trust all mrconfig files even if they are not listed in ~/.mrtrust.
+Use with caution.
-=head1 FILES
+=item -p
-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.
+=item --path
+
+This obsolete flag is ignored.
+
+=back
+
+=head1 MRCONFIG FILES
Here is an example .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.
+paths. (Note that you can use environment variables in section names; they
+will be passed through the shell for expansion. For example,
+"[$HOSTNAME]", or "[${HOSTNAME}foo]")
Within a section, each parameter defines a shell command to run to handle a
given action. mr contains default handlers for "update", "status",
=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
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
+present, mr assumes it is in offline mode.
+
+=head1 EXTENSIONS
+
+mr can be extended to support things such as unison and git-svn. Some
+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.
