SUMMARY = "XCB: The X protocol C binding headers"
DESCRIPTION = "Function prototypes for the X protocol C-language Binding \
(XCB).  XCB is a replacement for Xlib featuring a small footprint, \
latency hiding, direct access to the protocol, improved threading \
support, and extensibility."

# rebuilds.  Solve this by deleting the entire cache directory when this package
