+(** select metasenv conjecture pattern

+* It returns the set of matched terms (that can be compared using physical
+* equality to the subterms of [conjecture]) together with their contexts.
+* The representation of the set mimics the conjecture type (but for the id):
+* a list of (possibly removed) hypothesis (without their names) together with
+* the list of its matched subterms (and their contexts) + the list of matched
+* subterms of the conclusion with their context. Note: in the result the list
+* of hypotheses * has an entry for each entry in the context and in the same
+* order. Of course the list of terms (with their context) associated to one
+* hypothesis may be empty. *)
