+Here is a brief explanation on how to sync Mesa in trunk base.
+
+Current version is 8.0.4
+
+- SOURCE FILES :
+________________
+
+All unnecessary files and directories where removed from the tree, as it's already a
huge piece of code.
+
+ - build tools (bin, configs, scons, src/gallium/tools) were removed, as we don't use
it.
+ - documentation (docs, src/gallium/docs, doxygen) were removed. If you want to
contribute to libMesa, you'd better use their build system, not our adapted one
+ - tests and testing tools were removed (test, src/gallium/tests, src/gallium/tools)
+ - egl functionality (src/egl) is useless to us and were removed.
+ - gbm functionality (src/gbm) is useless to us and were removed.
+ - getopt implementation (src/getopt, for MSVC compatibility) is useless to us, we
already have one
+ - glx (src/glx) functionality is useless to us and were removed.
+ - src/gallium
+   - All gallium drivers (src/gallium/driver) where deleted, except for the softpipe 
one.
+   - All gallium state trackers (src/gallium/state_trackers) were removed, except for the
wgl one
+   - All gallium targets (src/gallium/targets) were removed, except for the libgl-gdi
one.
+   - All gallium window system backends (src/gallium/winsys) were removed, except for the
gdi one (sw/gdi)
+ - src/mapi
+   - only mapi and glapi directories were relevant and kept
+ - src/mesa
+   - All MESA drivers where deleted (src/mesa/drivers), except for the "common"
part and osmesa (off-screen mesa) library.
+   - Architecture specifics were removed. x86 and x86_64 might be restored in future
+ - src/glu where kept and will be used for the glu32 dll implementation
+
+
+- GENERATED FILES:
+__________________
+
+libMesa build system generates source files (using scons).
+They were taken from an out-of-source build an put in the "generated"
directory, using the same 
+directory structure for the sake of ease of maintainability.
+
+
+- CMAKELISTS FILES:
+___________________
+
+Those files were written using the Sconscript and source list files as reference. I think
that diff-ing them between two 
+versions would permit to easily update the cmake configuration files.
