+ # On HPUX 10.x, the parts of X that HP considers "standard" live in
+ # /usr/{include,lib}/X11R6/. The parts that HP doesn't consider
+ # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
+ # Yet /usr/contrib/X11R6/ comes preinstalled on all HPUX systems.
+ # Also, there are symlinks from /usr/include/ and /usr/lib/ into
+ # /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
+ # you don't need any -I or -L arguments.
+ #
+ # On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
+ # are the same division as 10.x. However, there are no symlinks to
+ # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
+ # arguments are always necessary.
+ #
+ # However, X11R6 was available on HPUX 9.x as a patch: if that
+ # patch was installed, then all of X11R6 went in to
+ # /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
+ #
+ # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
+ # whether R5 was available as a patch; R6 undoubtedly was not.)
+ #
+ # So. We try and use the highest numbered pair of
+ # /usr/{include,lib}/X11R?/ and /usr/contrib/X11R?/{include,lib}/
+ # that are available. We do not mix and match different versions
+ # of X.

+ # X11R6, or did it include Xaw and Xmu as well? If the former,
+ # where did one find Xaw and Xmu on 9.x R6 systems? Would this
