## Compiler API service requires swiftmodule files to import shared libraries.
## This script builds those swiftmodule files used by Compile API service.
## This SwiftPM package is a collection of shared libraries and PreviewStub
## target is an anchor to build whole dependencies.
##
## The output artifact structure is:
## distribution
## ├── library.so.wasm
## └── PreviewStub
## ├── checkouts
## │ ├── JavaScriptKit
## │ ├── ...
## │ └── Tokamak
## └── wasm32-unknown-wasi
## ├── JavaScriptKit.swiftmodule
