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

428 # * On HPUX 9.x, where /usr/include/X11R5/ was standard, and
429 # /usr/contrib/X11R6/ could be installed as a patch, what was in
430 # that contrib directory? Did it contain so-called "standard"
431 # X11R6, or did it include Xaw and Xmu as well? If the former,
432 # where did one find Xaw and Xmu on 9.x R6 systems? Would this
