# Though google-api-go-generator is a main, dex vendors the app using the same
# tool it uses to vendor third party packages. Hence, it can be found in the
# "vendor" directory.
#
# This vendoring is currently done with godep, but may change if/when we move to
# another tool.
#
# See schema/generator_import.go for instructions on updating the dependency.
