# This script is run in a git repository. It lists all header files,
# sorted by the number of other files where the file name of the file
# occurs. It is intentionally not limited to only source files, and
# there may be some false hits because we search only for the file
# part (sans directory). It is quite slow.
# Headers close to the top of the list are candidates for removal.
