-The standard location for the OpenGL header files on Unix-type systems is
-in <code>/usr/include/GL/</code>.
-The standard location for the libraries is <code>/usr/lib/</code>.
-For more information see, the
-<a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
-Linux/OpenGL ABI specification</a>.
-</p>
-
-<p>
-If you'd like Mesa to co-exist with another implementation of OpenGL that's
-already installed, you'll have to choose different directories, like
-<code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
-</p>
-
-<p>
-To install Mesa's headers and libraries, run <code>make install</code>.
-But first, check the Mesa/configs/default file and examine the values
-of the <b>INSTALL_DIR</b> and <b>DRI_DRIVER_INSTALL_DIR</b> variables.
-Change them if needed, then run <code>make install</code>.
-</p>
-
-<p>
-The variable
-<b>DESTDIR</b> may also be used to install the contents to a temporary
-staging directory.
-This can be useful for package management.
-For example: <code>make install DESTDIR=/somepath/</code>
-</p>
-
-<p>
-Note: at runtime you can use the LD_LIBRARY_PATH environment variable
-(on Linux at least) to switch
-between the Mesa libraries and other vendor's libraries whenever you want.
-This is a handy way to compare multiple OpenGL implementations.
