# This file provides targets 'deb' and 'debfile'.
#
# - debfile - produces a 'packagename.debequivs' file, which can be
#             processed by program 'equivs-build' inside Debian package
#             'equivs'. Such processing will produce file named
#             gomoku_1.1.1_i386.deb (for example).
# - deb     - runs 'equivs'build.
#
# Processor architecture is detected from output of $(CC) -dumpmachine.
# If $(CC) is not defined, gcc is used.

# [1] Add - after common.make - the following lines in your GNUmakefile:
#
# PACKAGE_NAME = Gomoku
# PACKAGE_VERSION = 1.1.1
# 
# The other important variable you may want to set in your makefiles is
#
# GNUSTEP_INSTALLATION_DOMAIN - Installation domain (defaults to LOCAL)
#
# A special note: if you need `./configure' to be run before
# compilation (usually only needed for GNUstep core libraries
# themselves), define the following make variable:
#
# PACKAGE_NEEDS_CONFIGURE = yes
#
# in your makefile.
