+= About =
+
+This directory contains the common code for the Gallium 3D remote debugging
+driver and clients. The code is two parts the connection managment code and
+the (de)marsheller.
+
+The code currently uses tcp and ip4v for connections.
+
+Information about driver integration can be found in:

+src/gallium/drivers/trace/README
