##  This makefile was modified March 1994 at the Naval Research Laboratory.
##  NRL additions/modifications to the standard S/Key distribution include:
##      * A modified BSD FTP daemon that does S/Key
##      * The "su" binary always does S/Key, even on the console. 
##	  This was a hole on rlogin/telnet sessions in the original software.
##      * MD5 support (MD5 seemed to work out of the box.)
##	  MD5 is believed by many to be stronger than MD4, see the RFCs.
##      * Cosmetic changes
##
##  Additional modifications from Marcus Ranum <mjr@tis.com> are described
##  in the README.MJR file included in this distribution.  Those mods are
##  only enabled if you add the text "-DMJR" to the CFLAGS.
##
##  Search for "NRL" to see the various changes done by Dan McD. at NRL.

## CONFIGURATION PARAMETERS.  Change these to suit your machine.

# LBIN is the place where user-installed binaries reside.
LBIN=/usr/local/bin

# FTPDIR is where the FTP daemon resides.  FTPDNAME is the name of the
# daemon which resides in FTPDIR.
FTPDIR = /usr/etc
FTPDNAME = in.ftpd

# SYSBIN is where the system binaries "su" and "login" reside.
SYSBIN = /bin

# Uncomment the lines below beginning with "DES" if you are using the MJR
# variant.  See README.MJR for more details.
#DESINCLUDE=	../libdes
#DESLIB=	$(DESINCLUDE)/libdes.a
#DESFLAGS=	-I$(DESINCLUDE)

### Note:  To select between MD4 and MD5, look at the "Take your pick"
###        comments scattered throughout.  Some lines need to be uncommented
###        and other to be commented.

# If you have an ANSI C compiler, uncomment the top line.
#CDEBUGFLAGS= -DPROTOTYPES=1
CDEBUGFLAGS= $(CONSTANTS)
#CDEBUGFLAGS= -O --- do NOT use -O, it causes different output
