# Creates a component for a library fuzzer.
#
# The component created by this template correspond to the binary created by an invocation of
# `fuchsia_library_fuzzer`.
#
# Parameters:
#   Same as `fuchsia_test_component`, except for `manifest`:
#     manifest (optional)
#       [path] The component manifest. Only CML manifests are supported. If omitted, the template
#       will generate a manifest using metadata added by `fuchsia_library_fuzzer` deps.
