-"""wrapper around emcc link step.
-
-This wrapper currently serves the following purposes.
-
-1. When building with --config=wasm the final output is multiple files, usually
- at least one .js and one .wasm file. Since the cc_binary link step only
- allows a single output, we must tar up the outputs into a single file.
-
-2. Add quotes around arguments that need them in the response file to work
- around a bazel quirk.
-
-3. Ensure the external_debug_info section of the wasm points at the correct
- bazel path.

-"""Unpackages a bazel emscripten archive for use in a bazel BUILD rule.
-
-This script will take a tar archive containing the output of the emscripten
-toolchain. This file contains any output files produced by a wasm_cc_binary or a
-cc_binary built with --config=wasm. The files are extracted into the given
-output path.
-
-The name of archive is expected to be of the format `foo` or `foo.XXX` and
-the contents are expected to be foo.js and foo.wasm.
-
-Several optional files may also be in the archive, including but not limited to
-foo.js.mem, pthread-main.js, and foo.wasm.map.
-
-If the file is not a tar archive, the passed file will simply be copied to its
-destination.
-
-This script and its accompanying Bazel rule should allow you to extract a
-WebAssembly binary into a larger web application.
