"""Archive helper script
This script acts as a frontend replacement for `ar`. See emcc.
This is needed because, unlike a traditional linker, emscripten can't handle
archive with duplicate member names. This is because emscripten extracts
archive to a temporary location and duplicate filenames will clobber each
other in this case.
