-About libxcb
-============
-
-libxcb provides an interface to the X Window System protocol, which
-replaces the current Xlib interface. It has several advantages over
-Xlib, including:
-- size: small, simple library, and lower memory footprint
-- latency hiding: batch several requests and wait for the replies later
-- direct protocol access: interface and protocol correspond exactly
-- proven thread support: transparently access XCB from multiple threads
-- easy extension implementation: interfaces auto-generated from XML-XCB
-
-Xlib can also use XCB as a transport layer, allowing software to make
-requests and receive responses with both, which eases porting to XCB.
-However, client programs, libraries, and toolkits will gain the most
-benefit from a native XCB port.

-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.
