//! The root module every user binary is compiled through (build.zig,
|
|
//! `addUserBinary`). The program's own file is imported as `program`, and this
|
|
//! shim contributes the declarations Zig resolves from the compilation root —
|
|
//! `main` (dispatched by runtime.start) and the panic handler — and pulls in the
|
|
//! `_start` entry shim. A program therefore only defines `pub fn main`; nothing
|
|
//! else is required in its source file.
