CPUSet V1.0 by Nic Wilson
-------------------------
This program is ShareWare. It may be freely distributed
on the condition that no profit is directly or indirectly
gained from its distribution. A donation is requested if
you find yourself using this utility.
Commercial Companies may also distribute it on their disks,
and a donation of either goods or monies is requested.
The program is hand coded in assembly language, so it
would be difficult if not impossible to write your own
any faster or smaller.
Progressive Peripherals & Software are exempt from all
distribution conditions and may distribute it in any
way they so desire.
The conditions below must be adhered to if you distribute
this program.
CONDITIONS
************************************************************
Crunching of this program as an executable crunched file is
not allowed, and is considered to contravene this agreement
of distribution. This has been done because the 68040
processor can crash if a program has been crunched.
Distribution in the form of 'LZH' file is acceptable.
This program and its document file must remain intact and
unmodified. Your own seperate document file may accompany
it.
************************************************************
