# This script expects that its first argument is the path prefix and the
# remaining ones are file paths. It generates a C source code containing
# the definition of the array of the 'FileToc' items. FileToc is a struct
# with two strings. The first is the file path with path prefix removed,
# and the second is the file contents as string. The last array element
# is a sentinel (both strings are null). One of the Kythe applications
# relies on this code (Kythe is the source code indexer: http://kythe.io/)
