Larch
     
        The Larch Project develops aids for formal specifications.
        Each Larch specification has two components: an interface
        containing predicates written in the LIL ({Larch Interface
        Language}) designed for the target language and a 'trait'
        containing assertions about the {predicate}s written in LSL,
        the {Larch Shared Language} common to all.
