# makefile for pjc's csh Copyright Julian H Stacey 21-8-89 @(#) Version 1.0
# supersedes all previous single op system makefiles and batch scripts,
# to be called from directory above in common with all berklix stuff.

# 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.
