>Environment:

	All environment.

>Description:

	I have hacked ln(1) and added -r and -a option.

	     -a    If the -s option is specified, make absolute symbolic link.
	     -r    If the -s option is specified, make relative symbolic link.
	     The -a and -r options override each other; the last one specified deter-
	     mines the method used.

	These options work like follows.

	% cd /usr/src/sys
	% ln -sfr kern/tty.c /usr/obj/usr/src/sys/kern
	% ls -l /usr/obj/usr/src/sys/kern/tty.c
	lrwxrwxrwx  1 shigio  bin  29 Jul 16 21:55 /usr/obj/usr/src/sys/kern/tty.c ->
					../../../../../src/kern/tty.c
					~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
					(right and relative symbolic link)

	% cd /usr/src/sys
	% ln -sfa kern/tty.c /usr/obj/usr/src/sys/kern
	% ls -l /usr/obj/usr/src/sys/kern/tty.c
	lrwxrwxrwx  1 shigio  bin  19 Jul 16 21:57 /usr/obj/usr/src/sys/kern/tty.c ->
					/usr/src/kern/tty.c
					~~~~~~~~~~~~~~~~~~~
					(right and absolute symbolic link)

	Note that both symbolic links are right.

>How-To-Repeat:

	It is not a bug but neither -r nor -a option specified, the result is

	% cd /usr/src/sys
	% ln -sf kern/tty.c /usr/obj/usr/src/sys/kern
	% ls -l /usr/obj/usr/src/sys/kern/tty.c
	lrwxrwxrwx  1 shigio  bin  10 Jul 16 21:59 /usr/obj/usr/src/sys/kern/tty.c ->
					kern/tty.c
					~~~~~~~~~~
					(wrong symbolic link)
	% cat /usr/obj/usr/src/sys/kern/tty.c
	cat: /usr/obj/usr/src/sys/kern/tty.c: No such file or directory

>Fix:
	
	Source code is here. It includes Makefile, related library source and
	online manuals too.
