PC-Lock V1.0-0
==============
Overview
---------
PC-Lock allows the user of a PC to 'Lock' a DOS session, thereby inhibiting
unauthorised usage of the machine during short absences such as lunchbreak.
The PC-Lock program prompts the user for a password (and re-prompts for
verification), and then prevents any further use of the machine until
the correct password is re-entered.
Once PC-Lock has activated (by entering a valid password and verification)
there are only 2 ways to de-activate it:
1: Enter the correct password
2: Re-boot the machine
Re-booting the machine is a rather ham-fisted way of gaining access to the
machine, and will be obvious to the legitimate user, who will then investigate
who has been using the machine in his absence.
