   =head1 TODO
   
   There are still a lot of commands that are not accessed directly.  If
   you call them (as cmd("command + args") or whatever) and it works,
   please send me examples that work and I will try to get it incorporated
   into the next version of the script.
   
   I also want to be able to parse the different types of output from
   commands like su, sudb all and anything else that would be better
   available as a perl datastructure.
