# Enhanced DR-DOS master Makefile for OpenWatcom WMAKE
# to build DRBIO.SYS, DRDOS.SYS and COMMAND.COM
#
# (c)opyright 2024 Bernd Boeckmann
#
# This makefile runs the make scripts of the individual components and
# puts the generated binaries into the bin directory

# By default it generates a compressed single-file kernel KERNEL.SYS.
# This may be altered via the make variables SINGLEFILE and COMPRESSED
#
# Call wmake SINGLEFILE=0 to generate a dual-file kernel consisting
# of DRBIO.SYS and DRDOS.SYS.
