 1. The overall bootstrapping process executes as follows
  - We first need an existing F# compiler. We use the one in the `lkg` directory. Let's assume this compiler has an `FSharp.Core.dll` with version X.
  - We use this compiler to compile the source in this distribution, to produce a "proto" compiler, dropped to the `proto` directory. When run, this compiler still relies on `FSharp.Core.dll` with version X.
