'' Hello there.  Peachy here.  This was a little game I cooked up while being
'' bored to tears on an IT traineeship this summer ('98).  While writing it
'' I thought it was great.  THEN I came and saw what some other ABC
'' programmers had done!  Great work guys and gals.  It makes this game look
'' puny.  (Most things look this game look puny!)
'' Errr...e-mail me with critisism (please!): Peachy512@yahoo.com
'' or visit my message board with some kind remarks and some funny thoughts
'' http://www.insidetheweb.com/messageboard/mbs.cgi/mb101664
'' Thanks.
