  Adventure Game Interpreter
  Original IBM PC version by Jeff Stephenson and Cris Iden
  of Sierra On-Line Inc. Around 1984-1989.
  
  JavaScript version by Erik Sandberg, 2014 (30th-ish anniversary!).
  This interpreter parses the original game resource files.
  I do not provide these files as they are the intellectual property of Sierra.
  
  This is not a straight port, but has been implemented from the specs
  defined by Lance Ewing, Peter Kelly, Claudio Matsuoka, Stu George and David Symonds
  at http://wiki.scummvm.org/index.php/AGI/Specifications
