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 predicates written in LSL,
the Larch Shared Language common to all.
