-- Accepts a limit (as in compilation or show usage) and builds the
-- necessary data structures to make enquiries.
-- There are two items of interest, limit specifiers and contexts.
-- A limit specifier specifies how to interpret a 'context'.
-- A context is a set of directory.objects, and is interpreted as directed
-- by the limit string. For example, if the limit string is
-- <WORLDS>, all objects in the same worlds as the contexts are ok.
-- Since there can be many contexts, many worlds can be specified.
-- The valid limit strings are:
--
-- <UNITS> Exact match of context(s)
-- <SUBUNITS> Context(s) and all subunits
-- <DIRECTORY> <DIRECTORIES> Library containing the context(s)
-- <WORLDS> World containing the context(s)
-- <ALL_WORLDS> Anything
-- <ACTIVITY> Worlds in the default activity
-- are used as context. Implies
-- <WORLDS>
-- Any naming string/set. The objects specified by the
-- expression. If an activity is
-- given, it is decomposed. The
-- change limit is set to the
-- 'highest' object encountered
-- (object, library, world)
--
-- Prefixes of the limit strings are accepted
