    (synopsis "Syntactic parser for several language")
    (description
     "Link Grammar is a syntactic parser of English, Russian, Arabic and
Persian (and other languages as well), based on Link Grammar, an original
theory of syntax and morphology.  Given a sentence, the system assigns to it a
syntactic structure, which consists of a set of labelled links connecting
pairs of words.  The parser also produces a \"constituent\" (HPSG style phrase
tree) representation of a sentence (showing noun phrases, verb phrases,
etc.). ")
