# This Makefile fragment is included by packages that require a run-time
# dependency on a ghostscript Postscript interpreter.
#
# To use this Makefile fragment, simply:
#
# (1) Optionally set GHOSTSCRIPT_REQD to the minimum version number of
#     Ghostscript required by the package,
# (2) Optionally set USE_GHOSTSCRIPT to "build" to only add a build-time
#     dependency on Ghostscript,
# (3) And include this Makefile fragment in the package Makefile,
