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."

# Need to do this dance because we're forcing the use of host Python above and

# Py3.6 the second build will write new cache files into the sysroot which won't
# be listed in the manifest so won't be deleted, resulting in an error on
# rebuilds.  Solve this by deleting the entire cache directory when this package
# is removed from the sysroot.
