-<h2>Automatic Code Generation</h2>
-
-<p>
-Starting from release 1.1.0, the source code and parts of the
-documentation are automatically generated from the extension
-specifications in a two-step process. In the first step,
-specification files from the OpenGL registry are downloaded and
-parsed. Skeleton descriptors are created for each extension. These
-descriptors contain all necessary information for creating the source
-code and documentation in a simple and compact format, including the
-name of the extension, url link to the specification, tokens, function
-declarations, typedefs and struct definitions. In the second step,
-the header files as well as the library and glewinfo source are
-generated from the descriptor files. The code generation scripts are
-located in the <tt>auto</tt> subdirectory.
-</p>
-
-<p>
-The code generation scripts require GNU make, wget, and perl. On
-Windows, the simplest way to get access to these tools is to install
-<a href="http://www.cygwin.com/">Cygwin</a>, but make sure that the
-root directory is mounted in binary mode. The makefile in the
-<tt>auto</tt> directory provides the following build targets:
-</p>
-
-<table border=0 cellpadding=0 cellspacing=5>
-<tr><td align="left" valign="top"><tt>make</tt></td>
-<td align=left>Create the source files from the descriptors.<br/> If the
-descriptors do not exist, create them from the spec files.<br/> If the spec
-files do not exist, download them from the OpenGL repository.</td></tr>
-<tr><td align="left" valign="top"><tt>make&nbsp;clean</tt></td>
-<td align=left>Delete the source files.</td></tr>
-<tr><td align="left" valign="top"><tt>make&nbsp;clobber</tt></td>
-<td align=left>Delete the source files and the descriptors.</td></tr>
-<tr><td align="left" valign="top"><tt>make&nbsp;destroy</tt></td>
-<td align=left>Delete the source files, the descriptors, and the spec files.</td></tr>
-<tr><td align="left" valign="top"><tt>make&nbsp;custom</tt></td>
-<td align=left>Create the source files for the extensions
-listed in <tt>auto/custom.txt</tt>.<br/> See "Custom Code
-Generation" below for more details.</td></tr>
-</table>
-
-<h3>Adding a New Extension</h3>
-
-<p>
-To add a new extension, create a descriptor file for the extension in
-<tt>auto/core</tt> and rerun the code generation scripts by typing
-<tt>make clean; make</tt> in the <tt>auto</tt> directory.
-</p>
-
-<p>
-The format of the descriptor file is given below. Items in
-brackets are optional.
-</p>
-
-<p class="pre">
-&lt;Extension Name&gt;<br>
-[&lt;URL of Specification File&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;[&lt;Token Name&gt; &lt;Token Value&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;[&lt;Token Name&gt; &lt;Token Value&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;...<br>
-&nbsp;&nbsp;&nbsp;&nbsp;[&lt;Typedef&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;[&lt;Typedef&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;...<br>
-&nbsp;&nbsp;&nbsp;&nbsp;[&lt;Function Signature&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;[&lt;Function Signature&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;...<br>
-<!-- &nbsp;&nbsp;&nbsp;&nbsp;[&lt;Function Definition&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;[&lt;Function Definition&gt;]<br>
-&nbsp;&nbsp;&nbsp;&nbsp;...<br> -->
-</p>
-
-<!--
-<p>
-Note that <tt>Function Definitions</tt> are copied to the header files
-without changes and have to be terminated with a semicolon. In
-contrast, <tt>Tokens</tt>, <tt>Function signatures</tt>, and
-<tt>Typedefs</tt> should not be terminated with a semicolon.
-</p>
--->
-
-<p>
-Take a look at one of the files in <tt>auto/core</tt> for an
-example. Note that typedefs and function signatures should not be
-terminated with a semicolon.
-</p>
-
-<h3>Custom Code Generation</h3>
-<p>
-Starting from GLEW 1.3.0, it is possible to control which extensions
-to include in the libarary by specifying a list in
-<tt>auto/custom.txt</tt>. This is useful when you do not need all the
-extensions and would like to reduce the size of the source files.
-Type <tt>make clean; make custom</tt> in the <tt>auto</tt> directory
-to rerun the scripts with the custom list of extensions.
-</p>
-
-<p>
-For example, the following is the list of extensions needed to get GLEW and the
-utilities to compile.
-</p>
-
-<p class="pre">
-WGL_ARB_extensions_string<br>
-WGL_ARB_multisample<br>
-WGL_ARB_pixel_format<br>
-WGL_ARB_pbuffer<br>
-WGL_EXT_extensions_string<br>
-WGL_ATI_pixel_format_float<br>
-WGL_NV_float_buffer<br>
-</p>
-
-<h2>Multiple Rendering Contexts (GLEW MX)</h2>
-
-<p>Starting with release 1.2.0, thread-safe support for multiple
-rendering contexts, possibly with different capabilities, is
-available. Since this is not required by most users, it is not added
-to the binary releases to maintain compatibility between different
-versions. To include multi-context support, you have to do the
-following:</p>
-<ol>
-<li>Compile and use GLEW with the <tt>GLEW_MX</tt> preprocessor token
-defined.</li>
-<li>For each rendering context, create a <tt>GLEWContext</tt> object
-that will be available as long as the rendering context exists.</li>
-<li>Define a macro or function called <tt>glewGetContext()</tt> that
-returns a pointer to the <tt>GLEWContext</tt> object associated with
-the rendering context from which OpenGL/WGL/GLX calls are issued. This
-dispatch mechanism is primitive, but generic.
-<li>Make sure that you call <tt>glewInit()</tt> after creating the
-<tt>GLEWContext</tt> object in each rendering context. Note, that the
-<tt>GLEWContext</tt> pointer returned by <tt>glewGetContext()</tt> has
-to reside in global or thread-local memory.
-</ol>
-
-<p>Note that according to the <a
-href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/opengl/ntopnglr_6yer.asp">MSDN
-WGL documentation</a>, you have to initialize the entry points for
-every rendering context that use pixel formats with different
-capabilities For example, the pixel formats provided by the generic
-software OpenGL implementation by Microsoft vs. the hardware
-accelerated pixel formats have different capabilities. <b>GLEW by
-default ignores this requirement, and does not define per-context
-entry points (you can however do this using the steps described
-above).</b> Assuming a global namespace for the entry points works in
-most situations, because typically all hardware accelerated pixel
-formats provide the same entry points and capabilities. This means
-that unless you use the multi-context version of GLEW, you need to
-call <tt>glewInit()</tt> only once in your program, or more precisely,
-once per process.</p>
-
-<h2>Separate Namespace</h2>
-
-<p>
-To avoid name clashes when linking with libraries that include the
-same symbols, extension entry points are declared in a separate
-namespace (release 1.1.0 and up). This is achieved by aliasing OpenGL
-function names to their GLEW equivalents. For instance,
-<tt>glFancyFunction</tt> is simply an alias to
-<tt>glewFancyFunction</tt>. The separate namespace does not effect
-token and function pointer definitions.
-</p>
-
-<h2>Known Issues</h2>
-
-<p>
-GLEW requires GLX 1.2 for compatibility with GLUT.
