!	ExpertGrammar.h, by Emily Short (emshort@mindspring.com) 
!
!	Being grammar statements and a couple of verbs to extend the standard
!	library with some of the most-requested improvements.  The most useful
!	of these are equivalences that the standard library doesn't understand --
!	GET DOWN for EXIT, DIG IN for DIG.  The rest are just spare verb stubs,
!	provided (in many cases) because some other standard authoring language
! 	has these verbs and yours truly has had a fit of jealousy.  Others
!	result from an inspection of the command logs on phpZork.  Bizarre though
!	some of these may seem to a seasoned adventurer ('but that's not an
!	IF word!!'), they are attested in actual play scripts.  Someone out
!	there has tried to use them...
!
!
!	Version 0.6 -- still in progress.  Let me know if you have 
!		more suggestions.

!	CONTENTS:
!
!	I would summarize, but they're pretty self-explanatory.  Page through
!	and have a look.  It's quite likely that you'll want to replace some
!	stubs and/or fiddle with the grammar lines.
!
!	INSTALLATION: 
!
!	Include "ExpertGrammar" after Grammar in your gamefile.
