-<h1>OpenGL ES</h1>
-
-<p>Mesa implements OpenGL ES 1.1 and OpenGL ES 2.0. More informations about
-OpenGL ES can be found at <a href="http://www.khronos.org/opengles/"
-target="_parent"> http://www.khronos.org/opengles/</a>.</p>
-
-<p>OpenGL ES depends on a working EGL implementation. Please refer to
-<a href="egl.html">Mesa EGL</a> for more information about EGL.</p>
-
-<h2>Build the Libraries</h2>
-<ol>
-<li>Run <code>configure</code> with <code>--enable-gles-overlay</code> and enable the Gallium driver for your hardware.</li>
-<li>Build and install Mesa as usual.</li>
-</ol>
-
-Alternatively, if XCB-DRI2 is installed on the system, one can use
-<code>egl_dri2</code> EGL driver with OpenGL|ES-enabled DRI drivers
-
-<ol>
-<li>Run <code>configure</code> with <code>--enable-gles1 --enable-gles2</code>.</li>
-<li>Build and install Mesa as usual.</li>
-</ol>
-
-<p>Both methods will install libGLESv1_CM, libGLESv2, libEGL, and one or more
-EGL drivers for your hardware.</p>
-
-<h2>Run the Demos</h2>
-
-<p>There are some demos in <code>progs/egl/</code>. You can use them to test
-your build. For example,</p>
-
-<pre>
- $ cd progs/egl/eglut
- $ make
- $ cd ../opengles1
- $ make
- $ ./torus_x11
-</pre>

-<h3>Dispatch Table</h3>
-
-<p>OpenGL ES has an additional indirection when dispatching fucntions</p>
-
-<pre>
- Mesa: glFoo() --&gt; _mesa_Foo()
- OpenGL ES: glFoo() --&gt; _es_Foo() --&gt; _mesa_Foo()
-</pre>
-
-<p>The indirection serves several purposes</p>
-
-<ul>
-<li>When a function is in Mesa and the type matches, it checks the arguments and calls the Mesa function.</li>
-<li>When a function is in Mesa but the type mismatches, it checks and converts the arguments before calling the Mesa function.</li>
-<li>When a function is not available in Mesa, or accepts arguments that are not available in OpenGL, it provides its own implementation.</li>
-</ul>
-
-<p>Other than the last case, OpenGL ES uses <code>APIspec.xml</code> to generate functions to check and/or converts the arguments.</p>
