+dnl @synopsis MDL_HAVE_OPENGL
+dnl 
+dnl Search for OpenGL.  We search first for Mesa (a GPL'ed version of
+dnl OpenGL) before a vendor's version of OpenGL, unless we were
+dnl specifically asked not to with `--with-Mesa=no' or `--without-Mesa'.
+dnl
+dnl The four "standard" OpenGL libraries are searched for: "-lGL",
+dnl "-lGLU", "-lGLX" (or "-lMesaGL", "-lMesaGLU" as the case may be) and
+dnl "-lglut".
+dnl
+dnl All of the libraries that are found (since "-lglut" or "-lGLX" might
+dnl be missing) are added to the shell output variable "GL_LIBS", along
+dnl with any other libraries that are necessary to successfully link an
+dnl OpenGL application (e.g. the X11 libraries).  Care has been taken to
+dnl make sure that all of the libraries in "GL_LIBS" are listed in the
+dnl proper order.
+dnl
+dnl Additionally, the shell output variable "GL_CFLAGS" is set to any
+dnl flags (e.g. "-I" flags) that are necessary to successfully compile
+dnl an OpenGL application.
+dnl
+dnl The following shell variable (which are not output variables) are
+dnl also set to either "yes" or "no" (depending on which libraries were
+dnl found) to help you determine exactly what was found.
+dnl
+dnl   have_GL
+dnl   have_GLU
+dnl   have_GLX
+dnl   have_glut
+dnl
+dnl A complete little toy "Automake `make distcheck'" package of how to
+dnl use this macro is available at:
+dnl
+dnl   ftp://ftp.slac.stanford.edu/users/langston/autoconf/ac_opengl-0.01.tar.gz
+dnl
+dnl Please note that as the ac_opengl macro and the toy example evolves,
+dnl the version number increases, so you may have to adjust the above
+dnl URL accordingly.
