There are a finite number of commands that can be found by
searching your $PATH.  Alias them all...  Or adjust the $PATH
so that a directory containing all the possible program names
symlinked to your program comes first.  The program can look
at the command line you entered to decide what to do next.  
Of course these won't work if the user types the full
path to the command.
