# Declares a fuzzer dictionary.
#
# This template generates a resource and provides the fuzzer-specific metadata for a fuzzer
# dictionary.
#
# This template is NOT typically used directly. Instead, use templates like `fuzzer` from
# //build/fuzzing/fuzzer.gni
#
# Parameters:
#
#   fuzzer (required)
#     [string] The name of the fuzzer.
#
#   label (required)
#     [label] The GN label of the associated fuzzer.
#
#   dictionary (required)
#     [path] The path to the dictionary file.
