# Partial makefile for Unix shared library target

#  make so		make ghostscript as a shared object
#  make sodebug		make debug ghostscript as a shared object
#  make soinstall	install shared object ghostscript
#  make soclean		remove build files
#
# If you want to test the executable without installing:
#  export LD_LIBRARY_PATH=/insert-path-here/sobin
#  export GS_LIB=/insert-path-here/lib
