make && go run cmd/ww/main.goThe make command uses go:generate to call tingo. See the //go:generate directive at the top of system/internal/main.go to see which command is run.
cmd/ww/main.go is the entrypoint for the ww command-line interface. It's not very interesting.
@lthibault recommends starting with ww.go in the repository's root directory. In particular, the Ww.Exec function sets up a wasm runtime, loads a blob of wasm bytecode (called a "ROM"), and executes it. When executing, the guest and host communicate over a Cap'n Proto rpc.Conn. The host connection is set up in Ww.Exec. The guest is set up in system/internal/main.go.
