-This module is used for building all custom go binaries within the cryptic-net
-project.
-
-The reason binaries are contained here, and not under the sub-directory for the
-sub-process the correspond to like most other code in this project, is that nix
-makes it difficult to compose multiple modules defined locally. If nix ever
-fixes this we should split this out.
