# DESCRIPTION
#
# This script first checks if the libfpl was not found by the src/configure
# script.
# If not, it scans the system for the libfpl file. If not found, it asks the
# user to enter a path in which it may find it, or the user can abort the
# search. If the library is found it modifies the config.h and src/Makefile
# to fully take advantage of fpl.
