[ InfixWelcomeSub;
  print "; Welcome to the ~Infix~ debugger (1/990428), which makes the
      following verbs available:^^
      ~; <expression>~: evaluates this Inform expression: e.g.
      ~; location~ will print the value of the variable ~location~,
      ~; 3*5+1~ will print 16, ~; children(old cloth bag)~ will tell you
      how many items are in it. (You can name objects either by their
      names inside the source code, such as ~n_obj~, or by typing the
      names by which the game's parser would normally know them, such
      as ~north wall~: the effect is the same.)^
      Any expression is allowed except that you can't use double-quoted
      strings of text: but you can send messages, call routines or
      assign values to variables, properties and array entries.
      ^   ~; score++~ is one way to get on in the world.
      ^   ~; deadflag = true~ is one way to get out of it.
      ^   ~; StopDaemon(nasty little dwarf)~ will keep you from being pestered.^
      Conditions like ~; score>20~ are also allowed and print
      either 1 (if true) or 0 (if false).^^";
  print "~;examine <something>~ or ~;x <something>~ gives full details
      of whatever it is. For instance, ~;x ##Take~ describes the Take
      action; ~;x Class~ the class Class; ~;x 'drop'~ the dictionary
      word ~drop~ and so on for numbers, routines, arrays and of course
      objects.  ~;xo~ examines something as an object, so for instance
      ~;x location~ tells you about the variable ~location~, but ~;xo
      location~ tells you what object it refers to.^^";
  print "~;give~, ~;remove~ and ~;move~ work like the corresponding
      Inform statements.^^";
  print "~;<~ causes an action: for instance, ~;< Eat cheese~.^^";
  print "~;watch~ or ~;w~ can set a watch on various activities:
      type just ~;w~ for details.^^";
  print "~;inventory~ or ~;i~ describes the contents of this story file.^";
