# 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
