B<mr> [options] log
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.

+parent directories.
These predefined commands should be fairly familiar to users of any revision
control system:

The mrconfig file that is modified is chosen by either the -c option, or by

=head1 MRCONFIG FILES
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.
+
+=head1 OFFLINE LOG FILE
-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.
+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.
