# NOTE: This target is used by "fx set --cargo-toml-gen ..." which

#
#  1) Ensure that "fx gen" (and "fx build") will pass `--ide-json`
#     to `gn gen`, which generates an up-to-date
#     `$root_build_dir/project.json` file, used here as input.
#
#  2) Add this target to the base packages list to ensure its
#     action script is run by "fx build".
