Allows you to build the
App instance from your Cargo.toml at compile time.
Equivalent to using the
crate_*! macros with their respective fields.
Provided separator is for the
refer to the documentation therefor.
NOTE: Changing the values in your
Cargo.toml does not trigger a re-build automatically,
and therefore won't change the generated output until you recompile.
Pro Tip: In some cases you can "trick" the compiler into triggering a rebuild when your
Cargo.toml is changed by including this in your
let m = app_from_crate!().get_matches();
