Will it allow programs to be EXECUTED, though? On many OSes,
one can execute anything one can read; that is, the permissions
are not separate. And if the program is a script, read permission
may be all that's necessary, because the script is really just
"data" for the interpreter.
P.S. -- We don't use GhostScript, because it's one of the few products
out there which has a license that's MORE onerous than the GPL. Viral...
