/// The argument parser is responsible for grouping positional arguments into
/// argument groups, which consist of a path to a recipe and its arguments.
///
/// Argument parsing is substantially complicated by the fact that recipe paths
/// can be given on the command line as multiple arguments, i.e., "foo" "bar"
/// baz", or as a single "::"-separated argument.
///
/// Error messages produced by the argument parser should use the format of the
/// recipe path as passed on the command line.
///
/// Additionally, if a recipe is specified with a "::"-separated path, extra
/// components of that path after a valid recipe must not be used as arguments,
/// whereas arguments after multiple argument path may be used as arguments. As
/// an example, `foo bar baz` may refer to recipe `foo::bar` with argument
/// `baz`, but `foo::bar::baz` is an error, since `bar` is a recipe, not a
/// module.
