      Packages which are built for this system but instead of being a full
      runtime dependency, only wrappers of all executables that reside in the
      <literal>bin</literal> directory are actually runtime dependencies.

      As soon as one of these wrappers is executed, the real package is fetched
      and the corresponding binary is executed.
