# quickjs-emscripten exposes an export for the .wasm file, but Cloudflare refuses to accept it.
# Cloudflare's build system only allows importing .wasm files using a relative path.
# Github issue: https://github.com/cloudflare/workers-sdk/issues/1672
#
# Instead the easy way out is to just copy the .wasm files we need into the build directory.
# Once there, we can import them and use them to make a new quickjs variant.
