 =head1 FILES
 
+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.
+
 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.
