+Introduction
+------------
+
+This document describes the implementation of the XFree86 4.0 libGL.so
+library defined by the Linux/OpenGL Base specification found at
+http://reality.sgi.com/opengl/linux/linuxbase.html.
+
+The documentation is divided into two sections:
+    User's Guide
+    Driver Developer's Guide

+User's Guide
+------------
+
+Using libGL.so
+
+The libGL.so library defines the gl- and glX-prefixed functions needed to
+run OpenGL programs.  OpenGL client applications should link with the
+-lGL option to use it.
+
+libGL.so serves two primary functions: GLX protocol generation for indirect
+rendering and loading/management of hardware drivers for direct rendering.
+
+When libGL.so initializes itself it uses the DRI to determine the
+appropriate hardware driver for each screen on the local X display.
+The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/
+directory.  Drivers are named with the convention <name>_dri.so where
+<name> is a driver such as "tdfx", "i810", "gamma", etc.
+
+The LIBGL_DRIVERS_DIR environment variable may be used to specify a
+different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/.
+This environment variable is ignored in setuid programs for security
+reasons.
+
+When libGL.so is unable to locate appropriate hardware drivers it will
+fall back to using indirect GLX rendering.
+
+To aid in solving problems, libGL.so will print diagnostic messages to
+stderr if the LIBGL_DEBUG environment variable is defined.
+
+libGL.so is thread safe.  The overhead of thread safety for common,
+single-thread clients is negligible.  However, the overhead of thread
+safety for multi-threaded clients is significant.  Each GL API call
+requires two calls to pthread_get_specific() which can noticably
+impact performance.  Warning:  libGL.so is thread safe but individual
+DRI drivers may not be.  Please consult the documentation for a driver
+to learn if it is thread safe.
+
+
+
+Indirect Rendering
+
+You can force indirect rendering mode by setting the LIBGL_ALWAYS_INDIRECT
+environment variable.  Hardware acceleration will not be used.
+
+
+
+libGL.so Extensibility
+
+libGL.so is designed to be extended without upgrading.  That is,
+drivers may install new OpenGL extension functions into libGL.so
+without requiring libGL.so to be replaced.  Clients of libGL.so should
+use the glXGetProcAddressEXT() function to obtain the address of
+functions by name.  For more details of GLX_ARB_get_proc_address see
+http://oss.sgi.com/projects/ogl-sample/registry/ARB/get_proc_address.spec
+
+libGL.so is also designed with flexibility such that it may be used
+with many generations of hardware drivers to come.

+Driver Developer's Guide
+------------------------
+
+This section describes the requirements to make an XFree86 4.0
+libGL.so-compatible hardware driver.  It is not intended for end
+users of libGL.so.
+
+
+XFree86 source files
+
+libGL.so is built inside XFree86 with sources found in xc/lib/GL/.
+Specifically, libGL.so is built from:
+
+	xc/lib/GL/glx/*.c
+	xc/lib/dri/XF86dri.c
+	xc/lib/dri/dri_glx.c
+	xc/lib/GL/mesa/src/glapi.c
+	xc/lib/GL/mesa/src/glapitemp.h
+	xc/lib/GL/mesa/src/glapitable.h
+	xc/lib/GL/mesa/src/glapioffsets.h
+	xc/lib/GL/mesa/src/glapinoop.c
+	xc/lib/GL/mesa/src/glheader.h
+	xc/lib/GL/mesa/src/glthread.c
+	xc/lib/GL/mesa/src/glthread.h
+	xc/lib/GL/mesa/src/X86/glapi_x86.S
+	xc/lib/GL/mesa/src/X86/assyntax.h
+
+Understand that the mesa/src/gl*.[ch] files are not tied to Mesa.  They
+have no dependencies on the rest of Mesa and are designed to be reusable
+in a number of projects.
+
+The glapi_x86.X and assyntax.h files implement x86-optimized dispatch
+of GL functions.  They are not required; C-based dispatch can be used
+instead, with a slight performance penalty.
