458	# "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
459	# Also, there are symlinks from /usr/include/ and /usr/lib/ into
460	# /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
461	# you don't need any -I or -L arguments.
462	#
463	# On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
464	# are the same division as 10.x. However, there are no symlinks to
465	# the X stuff from /usr/include/ and /usr/lib/, so -I and -L
466	# arguments are always necessary.
467	#
468	# However, X11R6 was available on HPUX 9.x as a patch: if that
469	# patch was installed, then all of X11R6 went in to

472	# HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
