! To register this module with your library, add the line:
!
!		#include "ORNPCVerb";					!Constant USE_ORNPCVerb; 
!	
!	to the library header file (OR_Library_Include).  To use in a game, add the line:

! Revision History
! 2002.02.17	Initial Creation (not really, but this was the earliest date I could 
!				find without searching my code archive)
! 2002.02.26	Fit to new template.
! 2002.05.12	Added versions of the BeforeRoutines() and AfterRoutines() routines.
! 2002.05.22	Fixed a problem with a nested call to the Orders routine from the 
!				BeforeRoutines routine.
! 2002.08.18	Wrapped all definitions in #ifndef pragmas so that they can be redifined
!				elsewhere.
! 2002.08.30	Restored Darkness test to GoSub.  Still trying to remember why it was 
!				removed at all...
! 2002.09.17	Added missed #ifndef pragma around ObjectIsUntouchable
! 2002.10.13	Added missed #ifndef pragma around PutOnSub and InsertSub
! 2002.12.24	Found bug in BeforeRoutines and AfterRoutines that caused the before/after 
!				method to be called on an object that contains an actor rather than the 
!				method attached to the top level room.
! 2003.02.28	Fixed bad representation of NPC wanderings up and down (e.g.: "Dan entered 
!				from the up.")
! 2003.03.01	Added code to the print message routine to prefix a newline the actor is 
!				not the player. Also made a minor modification to the TopLocation routine
!				to assume the actor if not parameter is provided.
! 2003.03.04	Fixed a little bug in the modification made 2/28/2003 which referenced
!				directions objects instead of direction properties (d_obj instead of d_to).
! 2003.03.11	Fixed some missing return values in the ORLibMessage object.
! 2003.03.13	Removed the diagnostic text that I put in and forgot to remove.
! 2004.01.11	Modified to match new stdlib 6.11
! 2004.02.05	Additional changes to better reflect stdlib enhancments.
! 2004.02.09	Even more additional changes to better reflect stdlib enhancments.
! 2004.02.27	Removed autodep code for ORRoutinesList, since it is no longer a requisite.
! 2004.03.03	Removed references to the ExtensionRunRoutines... routines.
! 2007.08.03    Howard Sherman added responses player should see when NPC wanders in or out
!               of a room (e.g. Billy wanders in from the out..." and so forth.
