# You must replace "ghostscript" and "GHOSTSCRIPT" with the lower case name and
# upper case name of your new package.  Some places below will say
# "Do not change this" - that does not include this global change,
# which must always be done to ensure we have unique names.

#
# GHOSTSCRIPT_VERSION, GHOSTSCRIPT_SITE and GHOSTSCRIPT_SOURCE define
# the upstream location of the source code for the package.
# GHOSTSCRIPT_DIR is the directory which is created when the source
# archive is unpacked.
# GHOSTSCRIPT_UNZIP is the command used to unzip the source.
# It is usually "zcat" (for .gz) or "bzcat" (for .bz2)
#
# You should change all these variables to suit your package.

# Flags such as LDFLAGS and CPPFLAGS should be passed into configure

# to Make causes it to override the default search paths of the compiler.

# If the compilation of the package requires other packages to be staged
## first, then do that first (e.g. "$(MAKE) <bar>-stage <baz>-stage").
