-"""
-The platform_data rule can be used to change the target platform of a target,
-and then depend on that elsewhere in the build tree. For example:
-load("@platforms//experimental/platform_data:defs.bzl", "platform_data")
-
-cc_binary(name = "foo")
-
-platform_data(
- name = "foo_embedded",
- target = ":foo",
- platform = "//my/new:platform",
-)
-
-py_binary(
- name = "flasher",
- srcs = ...,
- data = [
- ":foo_embedded",
- ],
-)
-
-Regardless of what platform the top-level :flasher binary is built for,
-the :foo_embedded target will be built for //my/new:platform.
-
-Note that if you depend on :foo_embedded it's not exactly the same as depending on :foo, since it won't forward all the same providers. In the future, we can extend this to add some common providers as needed."""
