What`s it all about?
--------------------

Every  Amiga  has a hardware build in to connect a lightpen to it.  However
this  feature  is  rarely  used,  so I decided to write a software to use a
lightpen  just  like  you  use the mouse.  You even can use the mouse and a
lightpen  simultaniously and your applications don`t notice any difference.
Unfortunately  the  resolution  of the light pen registers is not very high
(vertical 1 non-interlaced scan line, horizontal 2 low-res pixels), but for
normal menu selections and gadget pressing it is more than sufficient.

To use the handler

just plug in your lightpen in
		Joyport 1 (the right one) on an A2000
		Joyport 0 (the front one) on an A1000
and start the program from CLI or Workbench (you don`t need to RUN it).  To
remove  the  handler  just  run  it again.  If you start it from the CLI it
gives some output on what`s going on.  KS 2.0 should be no problem.  As you
may have noticed there is a difference between the A1000 and the A2000 (and
the other Amigas?):  On the A1000 you have to plug the lightpen in the same
port  the  mouse  goes.  To be still able to use the mouse you should first
run a program which attaches the mouse to the other port.
(However buttonsupport is hardwired for port1, but you can change it
to port0 in the source)
