#               INSTRUCTIONS
#               ============
# 0.  If you are porting to different hardware,
#     check the instructions in rcsbase.h
#
# Note: instructions 1-5 are normally taken care of by the calling make,
# which passes in DIFF, DIFF3, RCSDIR, OLDDIR, OS, and LOCKING.
#
# 1. Early version of diff did not support options needed by RCS.
#    Newer versions of diff, support them and diff is no longer distributed with
#    RCS. The following definitions apply only if you have both old versions
#    and new versions of diff, and you want RCS to use the new versions.

#    Figure out where to put the modified diff and diff3 commands, and
#     install them. (Read the instructions in the Make-files).
#     Define the macros DIFF and DIFF3 accordingly (below).
DESTDIR   =
DIFF      = /bin/diff
DIFF3     = /usr/libexec/diff3

# 2.  Figure out where to put the RCS commands; define RCSDIR accordingly.
RCSDIR    = /usr/new
MERGE     = $(RCSDIR)/merge

# 3.  Figure out where to put your old RCS commands; define OLDDIR
#     accordingly. This is not needed if you don't have an old release of RCS.
OLDDIR    = /usr/old/bin

# 4.  Set the operating system variable OS. If you run on 4.1 BSD, do not
#     define OS:
#     OS  =
#     If you run on USG Unix or UN*X, use:
#     OS  = -DUSG
#     If you run on Version 6 Unix, use:
#     OS  = -DV6
#     If you run on 4.2 or 4.3 BSD, use:
#     OS = -DV4_2BSD
OS        = -DV4_2BSD

# 5.  Decide whether you want strict locking as the default or not.
#     If you want strict locking, use:
#     LOCKING = 1
#     otherwise:
#     LOCKING = 0
LOCKING   = 1

# 6.  Decide what loader flags you need, and define LDFLAGS accordingly.
#     On the Vax you need none, on PDP-11s with split i/d you need -i.
SEPFLAG   = -i
LDFLAGS   = ${SEPFLAG}

# 7.  RCS can maintain a log of the use of the co and ci commands. If you
#     want the logging, you must
#     a) define SNOOP (that's where the process that writes the log goes),
#     b) define SNOOPFILE (that's the file where SNOOP writes the log;
#        it must be owned by the same user that owns SNOOP),
#     c) include SNOOP and SNOOPFILE in the CFLAGS macro.
#     If you don't want the logging of command usage, omit the SNOOP and
#     SNOOPFILE definitions from CFLAGS.
#     The two variants of the CFLAG macros are given below.
SNOOPFILE = /usr/log/rcslog/log
SNOOP	= /usr/local/bin/snoop


# On the PDP-11, define SMALLOG (-DSMALLOG in DEFINES) to reduce the
# maximum size of the log message and save memory.
#
DEFINES= $(OS) -DSTRICT_LOCKING=$(LOCKING) -DDIFF='"${DESTDIR}$(DIFF)"' -DMERGE='"${DESTDIR}$(MERGE)"' -DTARGETDIR='"${DESTDIR}$(RCSDIR)"' -DSMALLOG
CFLAGS	= -O $(DEFINES)
LINT = lint -c -u  -Dlint $(DEFINES)

# 8.  If you don't have release 2 RCS files around (e.g., if you don't
#     have release 2 of RCS), remove the word -DCOMPAT2 from whatever
#     variant of CFLAGS you selected. -DCOMPAT2 assures that release 2
#     RCS files can still be read. (After all release 2 RCS files have
#     been updated with release 3 or 4 ci or rcs, you can remake RCS without
#     -DCOMPAT2.) Also, make sure that the co commands at the end of this
#     file are commented out; otherwise, Make will complain.
#
# 9.  Now you are ready. Try to make 'all'. If all went well, make
#     'install' if you want no logging of command usage, 'installog' otherwise.
#
# 10. IMPORTANT! When you have RCS installed, rename old
#     release 2 RCS files as follows (if you have any):
#     If the working file was "f.c" and the RCS file "f.c.v", rename the
#     RCS file to "f.c,v". If the working file was "f.c" and the RCS file
#     "f.v", rename the RCS file "f.c,v". Thus, suffixes are no longer
#     dropped and RCS files end in ",v" rather than ".v".
#
# 11. If you want to maintain RCS with itself, be sure you preserve the
#     original revision numbers, dates, etc. This is done by checking the
#     files in with the -k option. When done, remove the comments from the
#     co-rules at the end of this file.
