#   Description:
#      Inventor include common rules - primary deals with generating a 
#   C-api from the .h files.  
#
#   The following should be set before including this file:
#	HINST_DIR	Directory under /usr that c++ header files should 
#			be installed in
#	CAPI_HINST_DIR  Directory under /usr that c header files should be
#			installed in
#	CPP_DIR		Directory relative to this one where c++ header files
#			can be stored
#	CAPI_DIR	Directory relative to this one where c header files can
#			be stored
#	CAPI_SOLIB	Destination location of C-api library
#	ORIG_DIR	Relative location of this directory to CPP_DIR and
#			CAPI_DIR
#	HFILES		All .h files to be processed
