 =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

-avoid worries about evil commands in a mrconfig file, mr
-has the ability to read mrconfig files in untrusted mode. Such files are

+inside a repository that your main ~/.mrconfig checks out. To

-By default, mr trusts all mrconfig files. (This default will change in a
