# Makefile to build the D runtime library core components for Posix
# Designed to work with GNU make
# Targets:
#	make
#		Same as make all
#	make debug
#		Build the debug version of the library
#   make release
#       Build the release version of the library
#   make doc
#       Generate documentation
#	make clean
#		Delete all files created by build process
