    I am releasing this as SHAREWARE.  I ask that if you enjoy it and
  want to encourage me to write more games for X (and I have a whole
  slew of Amiga games much better than this waiting to be ported)  you
  send me the paltry sum of FIVE DOLLARS.  Whether or not you send me
  the dough, you are free to distribute this archive provided all files
  are left intact, and no fees are charged other than a reasonable
  amount for the cost of distributing it (floppy disk, CD-rom, etc.)
  Note that libXsprite and mkimgsrc are covered by their own copyrights.
  
    The address to send your bribe for future games to is:
  
      Joe Rumsey
      3015 NW Market St. #B115                                                        
      Seattle, WA 98107

  That's $5 in United States money.  US Checks and Money Orders are
  fine.  The Post Office recommends that you not send cash, but I don't
  care, cash is fine too.
  
    My email address is ogre@atomic.com.
