Permissions are pretty straightforward -- for any process, I can specify the level of
permission of any group or user. Permission levels are Owner, Viewer, Execute, and None.
To determine the privilege level of a user against a particular process, I take the maximum
level afforded any of the groups the user belongs to. Note that since administrative tasks
will also be considered processes, we end up with a very flexible and powerful permission
system for all aspects of system administration. Processes which appear in this list are
those to which I have owner privilege. (If I'm an administrator, everything appears.)
