 | Well we hope you get a lot of use out of RAD.  Although RAD started        |
 | as a simple project by me (Shayde) it soon turned into something a lot     |
 | more complex and RAD would not be wot it is without the considerable       |
 | input from all members of Reality.  The graphics and a lot of design       :
 | ideas were put forward by Rogue (grafix artist) and Void (musician).       .
 | Because WE knew want we wanted out of a music development package, RAD     .
 | has evolved into something we are very happy to use for developing our
 | productions.  We hope you dudez also discover how to be RADical...!
