	This can be done with a group for the TA's and appropriate
	group permissions on the files, directories and programs they
	need to access.  Another group for operators, etc.  Under
	4.2bsd they can even belong to multiple groups simultaneously.
	All without setuid programs.

	Hey!  Lets not be lazy out there.
