+Mesa-5.1 release notes:
+-----------------------
+
+1) Glide2 support has been ceased; in order to keep Voodoo Graphics
+   and Voodoo Rush compatibility, please visit the Glide SourceForge
+   and help us to fix Glide3 for those cards.
+2) The current release is a WIP; among other things, the Linux build works
+   only to some extent. Any help will be appreciated.
+3) Glide3 can be found at http://sourceforge.net/projects/glide/
+
+
+
+Known supported HW/OS:
+----------------------
+
+Voodoo^2, Voodoo Banshee, Voodoo3, Voodoo4, Voodoo5
+DOS (DJGPP), Windows9x/2k (MinGW/MSVC), Linux
+
+
+
+How to compile:
+---------------
+
+DJGPP/MinGW/MSVC:
+   Place the Glide3 SDK in the top Mesa directory:
+	$(MESA)/glide3/include/*.h
+	$(MESA)/glide3/lib/
+   Required headers:
+	3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+   Required libraries:
+	OS specific
+   Type:
+	make -f Makefile.DJ HAVE_MMX=1 HAVE_3DNOW=1 FX=1
+	or
+	make -f Makefile.mgw HAVE_MMX=1 HAVE_3DNOW=1 FX=1
+	or
+	nmake -f Makefile.wfx
+   Look into the corresponding makefiles for further information.
+
+Linux:
+   Place the Glide3 SDK in /usr/local/glide
+   Type:
+	make linux-glide

 - No assembly code is compiled or assembled.  Again, this may need
   some work to turn it back on or use it again.
 
+- To build "mangled" Mesa, add the preprocessor define USE_MGL_NAMESPACE
+  to the project settings.  You will also need to edit src/mesa.def to change
+  all the gl* symbols to mgl*.  Because this is easy to do with a global
+  replace operation in a text editor, no additional mangled version of mesa.def
+  is maintained or shipped.
+
 If you have a Windows-related build problem or question, it is
 probably better to direct it to me (kschultz@users.sourceforge.net),
 rather than directly to the other Mesa developers.  I will help you

- *    SETUP_CODE      - to be executed once per triangle (usually HW init)
