If you want to port a MSDOS program that uses the microsoft mouse library,
the mousedriver has to be read by the application program, and the
application program moves the cursor on the screen. The application
program needs to know when the the mouse has been moved, or when a button is 
pressed. There is 2 solutions to this problem:
1)	Create a subprocess that is constantly reading the mousedriver
2)	The mousedriver sends a signal to the application program every time the
	mouse has moved or a button is pressed.

For several reasons, I think the latter solution is the more elegant the the
former.

Anyway, I think a mousedriver is needed for the MINIX operating system. Since
I am currently working on mousedriver implemtation on MINIX, I am quite happy
to post the specification of my own mousedriver as soon as I have time to do so.

ps. I am looking forward to see a more detailed specification of your mouse-
driver mr. Parkes.
