# Basic GNU -*-Makefile-*- to build GNU make
#
# NOTE:
# If you have no 'make' program at all to process this makefile:
#   * On Windows, run ".\buildw32.bat" to bootstrap one.
#   * On MS-DOS, run ".\builddos.bat" to bootstrap one.
#
# Once you have a GNU make program created, you can use it with this makefile
# to keep it up to date if you make changes, as:
#
#   make.exe -f Basic.mk
