Prerequire

• There is useless ability for use Git submodules with Nix flakes
  • It let us built Simula with the query, .?submodules=1#simula, from the nix build command.

Choices we can

• Then we can choose:
  1. Creates the Nix derivations from another repository. For now I chose this way.
  2. Creates the Nix derivations from local source code. The submodules will be replaced to normal source code, if we choose this way.
  3. Creates the Nix derivations from submodules' source code. This way has an problem which will let us built Simula with .?submodules=1#simula.
