-
-Locales -- Isar proof contexts as meta-level predicates, with local
-syntax and implicit structures.
-
-Draws basic ideas from Florian Kammueller's original version of
-locales, but uses the richer infrastructure of Isar instead of the raw
-meta-logic.  Furthermore, structured import of contexts (with merge
-and rename operations) are provided, as well as type-inference of the
-signature parts, and predicate definitions of the specification text.
-
-Interpretation enables the reuse of theorems of locales in other
-contexts, namely those defined by theories, structured proofs and
-locales themselves.
