=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
-respository. 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> is a tool to manage all your version control repos. 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, mercurial, bzr, darcs, fossil and veracity repositories, and support
+for other version 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,
-These predefined commands should be fairly familiar to users of any revision
+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 version
control system:

+Records changes to the local repository, but does not push them to the
+remote repository. Only supported for distributed version 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 version control systems.
+
=item diff
Show a diff of uncommitted changes.
Show the commit log.
+=item run command [param ...]

+=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.
+
+To use scp to download, the url may have the form ssh://[user@]host:file
+
+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 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.

=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.
=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 F<~/.mrconfig>
+as well as look for a F<.mrconfig> file in the current directory, or in one
+of its parent directories.
+
+=item -f
+
+=item --force
+
+Force mr to act on repositories that would normally be skipped due to their
+configuration.
=item -v
+=item --verbose
+
Be verbose.
+=item -q
+
+=item --quiet
+
+Be quiet. This suppresses mr's usual output, as well as any output from
+commands that are run (including stderr output). If a command fails,
+the output will be shown.
+
+=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 -n
+=item -i
-Just operate on the repository for the current directory, do not
-recurse into deeper repositories.
+=item --interactive
-=item -j number
+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.
-Run the specified number of jobs in parallel. This can greatly speed up
-operations such as updates. It is not recommended for interactive
-operations.
+=item -n [number]
-=back
+=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 F<~/.mrtrust>.
+Use with caution.

+will be passed through the shell for expansion. For example,
+C<[$HOSTNAME]>, or C<[${HOSTNAME}foo]>).

A few parameters have special meanings:
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.
+name in C<$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
+ [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 --force -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 F<.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, 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 among 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.
+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
+Unlike most other parameters, this can be specified multiple times, in
+which case the chunks of shell code are accumulatively concatenated
+together.
+
+=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 VCS_action
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.
+looks for a parameter named "VCS_action" (substituting in the name of the
+version control system and the action).
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 action that is performed for a given version control system, you can
+override these VCS specific actions. To add a new version control system,
+you can just add VCS specific actions for it.
+
+=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.
+
+=item _append
+
+Any parameter can be suffixed with C<_append>, to add an additional value
+to the existing value of the parameter. In this way, actions
+can be constructed accumulatively.
+
+=item VCS_test
+
+The name of the version control system is itself determined by
+running each defined "VCS_test" action, until one succeeds.
+
+=back
+
+=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 F<~/.mrconfig> checks out. To
+avoid worries about evil commands in a mrconfig file, mr defaults to
+reading all mrconfig files other than the main F<~/.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 F<~/.mrtrust>.
+One mrconfig file should be listed per line. Either the full pathname
+should be listed, or the pathname can start with F<~/> to specify a file
+relative to your home directory.
+
+=head1 OFFLINE LOG FILE
+
+The F<~/.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 F</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.
