# Declares a fuzzer corpus.
#
# This template provides the fuzzer-specific metadata for a fuzzer corpus.
#
# This template is NOT typically used directly. Instead, use templates like `fuzzer` from
# //build/fuzzing/fuzzer.gni
#
# Parameters:
#
#   label (required)
#     [label] The GN label of the associated fuzzer.
#
#   corpus (required)
#     [label] The GN label of the corpus. This is typically a `resource`. Use `fx fuzz update -h` to
#       get more information on generating such targets.
