# 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.
|
|
|
|
# If the name includes at most one directory, keep name unchanged,
|
|
# otherwise strip directories. Needed to work with relative #includes
|
|
# which are used in some parts of the tree, while still avoiding,
|
|
# e.g., api/foo.h to match includes of pc/foo.h.
