--- Installing the /usr/spool/uucp subdirectory kludge on system "xyz" ---
	(This assumes your uucp sources are in good shape,
	and are located in /usr/src/cmd/uucp.)

1.  Fixing up the syskludge files
1a) Mkdir /usr/src/cmd/uucp/syskludge, and chdir to it.
1b) Extract this tar file.
1c) Edit syskludge.c and change "D.duke" to "D.xyz".
1d) "make syskludge.a"

2.  Fixing up uucp
2a) chdir to /usr/src/cmd/uucp.
2b) Edit makefile and change "LIBS=" to "LIBS=syskludge/syskludge.a".
2c) Edit uucp.h and add "extern char *subdir();" at the end.
2d) Edit gnsys.c and append the following subroutine:

	/*
	 * return possibly corrected directory for searching
	 */
	char *
	subdir(d, pre)
	char *d, pre;
	{
		if (strcmp(d, Spool) == 0 && pre == CMDPRE)
			return("/usr/spool/uucp/C.");
		return(d);
	}

2e) Edit gnsys.c and "/fopen(dir,/s//fopen(subdir(dir, pre),/"
2f) Edit anlwrk.c and "/fopen(dir,/s//fopen(subdir(dir, pre[0]),/"
	(NOTE "pre" in gnsys.c, "pre[0]" in anlwrk.c)

3.  Finishing up.
3a) su root
3b) make
3c) make backup copies of uucp, uux, uucico, and uuxqt.
3d) WAIT UNTIL THERE IS NO UUCP TRAFFIC (single user is safest).
3e) Copy the new uucp, uux, uucico, uuxqt to the appropriate places.
3f) chdir to /usr/spool/uucp
3g) mkdir C. D. D.xyz; chmod 755 C. D. D.xyz
3h) chown uucp C. D. D.xyz; chgrp daemon C. D. D.xyz
3i) mv D.xyz?* D.xyz; mv D.?* D.; mv C.?* C.

4.  All done!  Mail a letter somewhere and see if it goes.
At your leisure, pack /usr/spool/uucp to remove the empty slots.

5.  Final notes:
5a. uulog, uuclean, and uuname are linked with LIBS, so they get changed.
You might want to copy them too, though there should be no functional change.
5b) If "C." is not a mapped prefix in syskludge.c, omit the "subdir()" kludge.
