#	g4bl-config --objs	echo list of G4beamline object files (no main)
#	g4bl-config --vcflags	echo list of flags for VC++ (Windows only)
#
#	This script must be run via an absolute pathname.
#
#	--dir and --sys do not need G4beamline source installed; the others 
#	require the source to be installed and configured.
#
#	This command is the source for various configuration items:
#	--include, --main, and --libs
#	The Makefile uses this command to get those, but it generates
#	its own list of objects from $SOURCE/src/*.cc
#	g4blmake uses this command to get --include, --main, --objs, and --libs.
#
#	NOTE: this command probably needs to be updated when a new version
#	of Geant4 is used (and possibly other libraries as well); especially
#	its --include and --libs.
