B<mr> [options] log
+B<mr> [options] run command [param ...]
+
B<mr> [options] bootstrap url [directory]
B<mr> [options] register [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.
+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:
Show the commit log.
+=item run command [param ...]
+
+Runs the specified command in each repository.
+
=back
These commands are also available:
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
=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>.
+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 --quiet
-Be quiet.
+Be quiet. This supresses 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
Trust all mrconfig files even if they are not listed in ~/.mrtrust.
Use with caution.
+=item -p
+
+=item --path
+
+This obsolete flag is ignored.
+
=back
=head1 MRCONFIG FILES
Unlike all other parameters, this parameter does not need to be placed
within a section.
+=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
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.
-
=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 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.
+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.
-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 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
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.
