# NOTE:  this makefile assumes that RMR has been built using the directory .build
#		at the top most repo directory (e.g. ../../.build). It can be changed
#		if you need to by adding "build_path=<path>" to the make command line.
#		To use this makefile to build on a system where RMR is already installed
#		try:    make build_path=/usr/local/lib
#
#		By default we prefer the Korn shell (it's just better). If you really need
#		to build with a dfferent shell add "SHELL=path" to the command line:
#				make SHELL=/bin/bash
