    Our goal is to encourage the use of definite clause grammars (DCGs)
    for describing strings. The predicates phrase_from_file/[2,3],
-   phrase_to_file/2 and phrase_to_stream/2 let us apply DCGs transparently
-   to files and streams, and therefore decouple side-effects from
-   declarative descriptions.
