#               INSTRUCTIONS
#               ============
#
# 0.  Do the instructions in rcsbase.h
#
# 1.  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).
DIFF      = /bin/diff
DIFF3     = /usr/lib/diff3

# 2.  Implant the macro DIFF3 as modified by you into the file merge.
#     (That's a shell file.)

# 3.  Figure out where to put the RCS commands; define TARGETDIR
#     and merge accordingly.
DESTDIR=
TARGETDIR = /usr/new
MERGE     = /usr/new/merge

# 4.  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.
#     Instead, comment out the 5 lines in INSTALLNO that mv the old RCS
#     commands to OLDDIR.
OLDDIR    = /usr/old

# 5.  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.
LDFLAGS   =
#LDFLAGS  = -i

# 6.  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/wft/RCSLOG/log
SNOOP     = /usr/wft/BIN/snoop
#CFLAGS    = -O -DCOMPAT2 -DDIFF='"$(DIFF)"' -DMERGE='"$(MERGE)"' -DTARGETDIR='"$(TARGETDIR)"' -DSNOOPFILE='"$(SNOOPFILE)"' -DSNOOP='"$(SNOOP)"'
CFLAGS   = -O -DDIFF='"$(DIFF)"' -DMERGE='"$(MERGE)"' -DTARGETDIR='"$(TARGETDIR)"' -DV4_2BSD

# 7.  If you don't have release 2 RCS files around (e.g., if you don't have
#     an old release 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 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.
#
# 8.  Now you are ready. Try to make all. If all went well, make
#     INSTALLW if you want the logging of command usage, INSTALLNO otherwise.
#
# 9.  IMPORTANT! When you have RCS installed, rename old 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".
#
# 10. 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.
