+o Updating XCB to a new release
+ -----------------------------
+
+libxcb uses C source files that are generated from the XML protocol
+specification using xcbgen, written in Python. On OpenBSD those files
+cannot be generated during a normal 'make build' since Python is not
+in the base system. So the generated version are checked in CVS
+(in lib/libxcb/src/). Here is the receipt to update them when updating
+to a new release of XCB:
+
+1) Update proto/xcb-proto.
+2) Update the x11/py-xcbgen port to the same version and install the
+ package.
+3) Update dist/libxcb.
+4) Check lib/libxcb/src/Makefile if new files need to be generated.
+5) Run 'make' in lib/xcb/src to generate the files for the new version.
+6) Check lib/libxcb/ for other files needing updates.
+7) Commit the result.
