+About xcb-proto
+===============
+
+xcb-proto provides the XML-XCB protocol descriptions that libxcb uses to
+generate the majority of its code and API. We provide them separately
+from libxcb to allow reuse by other projects, such as additional
+language bindings, protocol dissectors, or documentation generators.
+
+This separation between the XCB transport layer and the
+automatically-generated protocol layer also makes it far easier to write
+new extensions. With the Xlib infrastructure, client-side support for
+new extensions requires significant duplication of effort. With XCB and
+the XML-XCB protocol descriptions, client-side support for a new
+extension requires only an XML description of the extension, and not a
+single line of code.
+
+Python libraries: xcb-proto also contains language-independent Python
+libraries that are used to parse an XML description and create objects
+used by Python code generators in individual language bindings. These
+libraries are installed into $(prefix)/lib/pythonX.X/site-packages. If
+this location is not on your system's Python path, scripts that import
+them will fail with import errors. In this case you must add the
+install location to your Python path by creating a file with a `.pth'
+extension in a directory that _is_ on the Python path, and put the
+path to the install location in that file. For example, on my system
+there is a file named 'local.pth' in /usr/lib/python2.5/site-packages,
+which contains '/usr/local/lib/python2.5/site-packages'. Note that
+this is only necessary on machines where XCB is being built.
