# Inspired by qdp++-config from George T. Fleming
#
# Tool for retrieving configuration information about the installed version
# of QDP.
#
# This script was copied from the qdp++-config. The latter was
# inspired by many similar scripts available in RedHat Linux,
# including gnome-config, gtk-config and xmms-config.
#
# Be on the lookout for problems with undesirable CXXFLAGS and LDFLAGS
# propagating through this script.  Send email to flemingg@jlab.org
# if you find such a problem.
