+VMS support contributed by Jouk Jansen (joukj@hrem.stm.tudelft.nl)
+
+
+The latest version was tested on a VMSAlpha7.2 system using DECC6.0, but
+probably also works for other versions.
+
+At the moment only the libraries LIBMESGL.EXE/LIBMESGL.OLB,
+LIBMESAGLU.EXE/LIBMESAGLU.OLB and LIBGLUT.EXE/LIBGLUT.OLB and the demos of the
+directory [.DEMOS] can be build.
+However, feel free to create the missing "decrip.mms-files" in the other
+directories.
+
+ The make files were tested
+using the DIGITAL make utility called MMS. There is also a public domain
+clone available (MMK) and I think, but it is not tested, that this
+utility will give (hardly) any problem.
+
+To make everything just type MMS (or MMK) in the main directory of
+mesagl. For MMS the deafult makefile is called descrip.mms, and
+that is what I have called it. I included alse some config files,
+all having mms somewhere in the name which all the makefiles need
+(just as your unix makefiles).
+
+On Alpha platforms at default a sharable images for the libraries are created.
+To get a static library make it by typing MMS/MACRO=(NOSHARE=1).
+On VAX platforms only static libraries can be build.
+
+23-sep-2005
+changed default compilation to use /float=ieee/ieee=denorm. The reason for
+this is that it makes Mesa on OpenVMS better compatible with other platforms
+and other packages for VMS that I maintain.
+For more information see
+ http://nchrem.tnw.tudelft.nl/openvms
+ https://bugs.freedesktop.org/show_bug.cgi?id=4270
+You may want to compile Mesa to use VAX-floating point arithmetic, instead
+of IEEE floating point by removing the /float=IEEE/denorm flag from the
+compiler options in the descrip.mms files.
