# Interesting variables to define in your GNUmakefile:
#
# PACKAGE_NAME = gnustep-base
# VERSION = 1.0.0
#
# For CVS exports, you may want to define something like:
#
# CVS_MODULE_NAME = base
# CVS_FLAGS = -d :pserver:anoncvs@subversions.gnu.org:/cvsroot/gnustep
#
# You can also pass/override them on the command line if you want,
# make cvs-snapshot CVS_FLAGS="-d :pserver:anoncvs@subversions.gnu.org:/cvsroot/gnustep -z9"
#
# If you set the RELEASE_DIR variable, all generated .tar.gz files will 
# be automatically moved to that directory after having being created.
# RELEASE_DIR is either an absolute path, or a relative path to the 
# current directory.
#

# prevent multiple inclusions
