=head1 DESCRIPTION
-B<mr> is a Multiple Repository management tool. It allows you to register a
-set of repositories in a .mrconfig file, and then checkout, update, or
-perform other actions on all of the repositories at once.
+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.
+
+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,
-Any mix of revision control systems can be used with B<mr>, and you can
-define arbitrary actions for commands like "update", "checkout", or "commit".
+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.
-The predefined commands should be fairly familiar to users of any revision

+Checks out any repositories that are not already checked out.
=item update

+Updates each repository from its configured remote repository.
If a repository isn't checked out yet, it will first check it out.
=item status

=item commit (or ci)
-Commits changes to each registered repository. (By default, changes

+Commits changes to each repository. (By default, changes are pushed to the

+don't like this default, you can change it in your .mrconfig, or use record
+instead.)
+
+The optional -m parameter allows specifying a commit message.
+
+=item record
+
+Records changes to the local repository, but does not push them to the
+remote repository. Only supported for distributed revision control systems.
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.
+
+=item log
+
+Show the commit log.
+
=back
-Actions can be abbreviated to any unambiguous subsctring, so
-"mr st" is equivilant to "mr status".
+These commands are also available:
+
+=over 4
+
+=item bootstrap url
+
+Causes mr to download the url, save it to a .mrconfig file in the
+current directory, and then check out all repositories listed in it.
+
+=item list (or ls)
+
+List the repositories that mr will act on.
+
+=item register
+
+Register an existing repository in a mrconfig file. By default, the
+repository in the current directory is registered, or you can specify a
+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.
+
+=item config
+
+Adds, modifies, removes, or prints a value from a 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
+
+To see the built-in library of shell functions contained in mr:
+
+ mr config DEFAULT lib
+
+The ~/.mrconfig file is used by default. To use a different config file,
+use the -c option.
+
+=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
+
+Displays this help.
+
+=back
+
+Actions can be abbreviated to any unambiguous substring, so
+"mr st" is equivalent to "mr status", and "mr up" is equivalent to "mr
+update"
+
+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.
=head1 OPTIONS
=item -d directory
+=item --directory directory
+
Specifies the topmost directory that B<mr> should work in. The default is
-the current working directory. B<mr> will operate on all registered
-repositories at or under the directory.
+the current working directory.
=item -c mrconfig
-Use the specified mrconfig file, instead of looking for on in your home
-directory.
+=item --config mrconfig
+
+Use the specified mrconfig file. The default is B<~/.mrconfig>
+
+=item -p
+
+=item --path
+
+Search in the current directory, and its parent directories and use
+the first B<.mrconfig> found, instead of the default B<~/.mrconfig>.
=item -v
+=item --verbose
+
Be verbose.
-=back
+=item -q
-=head1 FILES
+=item --quiet
-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.
+Be quiet.
-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
-directory that contains the .mrconfig file.
+=item -s
-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
-environment, where any additional parameters you pass are available in
-"$@". B<mr> cds into the repository directory before running
-a command, except for the "checkout" command, which is run in the parent
-of the repository directory, since the repository isn't checked out yet.
+=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
-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.
-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 other commands
-can use.
+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.
-The "default" section allows setting up default handlers for each action,
-and is overridden by the contents of other sections. mr contains default
-handlers for the "update", "status", and "commit" actions, so normally
-you only need to specify what to do for "checkout".
+=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.
+
+If a number is specified, will recurse into repositories at most that many
+subdirectories deep. For example, with -n 2 it would recurse into ./src/foo,
+but not ./src/packages/bar.
+
+=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 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.
+
+=back
-The "alias" section allows adding aliases for commands. Each parameter
-is an alias, and its value is the command to run.
+=head1 "MRCONFIG FILES"
-For example:
+Here is an example .mrconfig file:
[src]
checkout = svn co svn://svn.example.com/src/trunk src
chain = true
[src/linux-2.6]
- skip = small
- checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
-
- [default]
- lib = \
- small() {
- case "$(hostname)" in; \
- slug|snail); \
- return 0; ;; ; \
- esac; \
- return 1; \
- }
+ checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git &&
+ cd linux-2.6 &&
+ git checkout -b mybranch origin/master
+
+The .mrconfig file uses a variant of the INI file format. Lines starting with
+"#" 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 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. (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",
+"commit", and other standard actions. 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
+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
+basename of the directory that should be created when checking the
+repository out.)
+
+The "MR_CONFIG" environment variable is set to the .mrconfig file
+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.
+
+A few parameters have special meanings:
+
+=over 4
+
+=item skip
+
+If the "skip" parameter is set and its command returns true, then B<mr>
+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" 12
+
+=item order
+
+The "order" parameter can be used to override the default ordering of
+repositories. The default order value is 10. Use smaller values to make
+repositories be processed earlier, and larger values to make repositories
+be processed later.
+
+Note that if a repository is located in a subdirectory of another
+repository, ordering it to be processed earlier is not recommended.
+
+=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.
+
+=item include
+
+If the "include" parameter is set, its command is ran, and should output
+additional mrconfig file content. The content is included as if it were
+part of the including file.
+
+Unlike all other parameters, this parameter does not need to be placed
+within a section.
+
+=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.
+
+=back
+
+When looking for a command to run for a given action, mr first looks for
+a parameter with the same name as the action. If that is not found, it
+looks for a parameter named "rcs_action" (substituting in the name of the
+revision control system and the action). The name of the revision control
+system is itself determined by running each defined "rcs_test" action,
+until one succeeds.
+
+Internally, mr has settings for "git_update", "svn_update", etc. To change
+the action that is performed for a given revision control system, you can
+override these rcs specific actions. To add a new revision control system,
+you can just add rcs specific actions for it.
+
+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.
+
+=head "UNTRUSTED MRCONFIG FILES"
+
+Since mrconfig files can contain arbitrary shell commands, they can do
+anything. This flexability 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 and chains to. To
+avoid worries about evil commands in a mrconfig file, mr
+has the ability to read mrconfig files in untrusted mode. Such files are
+limited to running only known safe commands (like "git clone") in a
+carefully checked manner.
+
+By default, mr trusts all mrconfig files. (This default will change in a
+future release!) But if you have a ~/.mrtrust file, mr will only trust
+mrconfig files that are listed within it. (One file per line.) All other
+files will be treated as untrusted.
+
+=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.
