524	# The following arcana was gleaned from conversations with
525	# Eric Schwartz <erics@col.hp.com>:
526	#
527	# On HPUX 10.x, the parts of X that HP considers "standard" live in
528	# /usr/{include,lib}/X11R6/. The parts that HP doesn't consider
529	# "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
530	# Yet /usr/contrib/X11R6/ comes preinstalled on all HPUX systems.
531	# Also, there are symlinks from /usr/include/ and /usr/lib/ into
532	# /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
533	# you don't need any -I or -L arguments.
534	#
535	# On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
536	# are the same division as 10.x. However, there are no symlinks to
537	# the X stuff from /usr/include/ and /usr/lib/, so -I and -L
538	# arguments are always necessary.
539	#
540	# However, X11R6 was available on HPUX 9.x as a patch: if that
541	# patch was installed, then all of X11R6 went in to
542	# /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
543	#
544	# HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
545	# whether R5 was available as a patch; R6 undoubtedly was not.)
546	#
547	# So. We try and use the highest numbered pair of
548	# /usr/{include,lib}/X11R?/ and /usr/contrib/X11R?/{include,lib}/
549	# that are available. We do not mix and match different versions
550	# of X.
551	#
552	# Question I still don't know the answer to: (do you?)
553	#
554	# * On HPUX 9.x, where /usr/include/X11R5/ was standard, and
555	# /usr/contrib/X11R6/ could be installed as a patch, what was in
556	# that contrib directory? Did it contain so-called "standard"
557	# X11R6, or did it include Xaw and Xmu as well? If the former,
558	# where did one find Xaw and Xmu on 9.x R6 systems? Would this
559	# be a situation where one had to reach into the R5 headers and
560	# libs to find Xmu? That is, must both R6 and R5 directories
561	# be on the -I and -L lists in that case?
