# makefile for pjc's nroff Copyright Julian H Stacey 21-8-89 @(#) Version 1.0
# (pjc never got round to writing one)

# This makefile works for both
#	1) berkley unix/make/bourne shell
#	2) msdos with a minix make that has been ported, and command.com.
# Do not change the syntax without checking on both machines.
