#
# Makefile for the backup system.  Since it isn't wise (or possible)
# to run setuid or setgid perl scripts, we use a C wrapper program
# that is setgid which runs perl on the script.  So installation
# consists of putting a bunch of scripts somewhere and in putting the
# compiled wrappers somewhere.  
#
# This Makefile provides several entries:
#	all		compiles the wrappers
#	install		copies the wrappers and scripts as needed to
#			the suitable places.
#	clean		removes junk from this directory
#	print		prints everything
#
# There are several variables here at the beginning that you might
# want to hack on.
#

#
# PERL is the pathname of perl as installed on your systems.
#
PERL =	/usr/athena/bin/perl

#
# SDIR is the directory in which all scripts should be placed.
#
SDIR =	/usr/local/backup/bin

#
# BDIR is the directory in which all binaries should be placed.
#
BDIR =	/usr/local/backup/bin

# 
# PERLLIBDIR is the directory in which Perl libraries should be placed.
# 
PERLLIBDIR = /usr/local/backup/lib/perl

#
# PRINTER is the name of the printer to print things to.  Note that
# the print: entry below uses 'enscript' and 'up' - you may need to
# change it to suit your environment (or get enscript and up!)
#
PRINTER =	meadow

#
# BACKUP is the name of the group that owns and can access the backup
# database files.  The backup programs run setgid to backup in the hopes
# that they will be able to write them.
#
BACKUP =	staff

#
# You might need to change these also...
#
RM =	/bin/rm
LN =	/bin/ln
CC =	/afs/athena/project/gnu/bin/gcc
CP =	/bin/cp
CHGRP =	/bin/chgrp
CHMOD =	/bin/chmod
#
# What strrchr to use - strrchr or rindex.
#
STRRCHR = strrchr			# Suns, Encore, HP, BBN Butterfly
#STRRCHR = rindex			# Pyramid
#
# What setreuid to use - define SETRESUID if this system uses it rather than
# setreuid.
#
#SETRESUID = 				# Sun, Encore, Pyramid, Butterfly
SETRESUID = -DNEED_SETUID		# Solaris
#SETRESUID = -DSETRESUID		# HP
