-# starlark_import package
-
-This allows soong to read constant information from starlark files. At package initialization
-time, soong will read `build/bazel/constants_exported_to_soong.bzl`, and then make the
-variables from that file available via `starlark_import.GetStarlarkValue()`. So to import
-a new variable, it must be added to `constants_exported_to_soong.bzl` and then it can
-be accessed by name.
-
-Only constant information can be read, since this is not a full bazel execution but a
-standalone starlark interpreter. This means you can't use bazel contructs like `rule`,
-`provider`, `select`, `glob`, etc.
-
-All starlark files that were loaded must be added as ninja deps that cause soong to rerun.
-The loaded files can be retrieved via `starlark_import.GetNinjaDeps()`.
