-# TODO(maruel): this file should live in third_party/nss but two factors get in
-# the way:
-# - .isolate files do not support conditional includes. This works in gyp by
-#   using the 'dependencies': [ 'path/to/file.gyp:project' ] which dynamically
-#   loads project files.
-# - third_party/nss is conditionally checked out. It is not checked out on
-#   linux.
