Flash is an attempt to create a secure menu-driver shell for UNIX-derived OSes,
while providing user-friendliness and easy configurability. An ideal situation
requiring the use of flash would be a student-run telnet server which needs to:

a) shelter the users from some of the nastinesses of UNIX
b) shelter the system from nasty users
c) provide an easy way to launch applications
d) support multitasking/job control as elegantly as possible
e) support easy-to-get-right configuration by administrators
