+The Isabelle/Isar theory format integrates specifications and
+ proofs, supporting interactive development with unlimited undo
+ operation. There is an integrated document preparation system (see
+ \chref{ch:document-prep}), for typesetting formal developments
+ together with informal text. The resulting hyper-linked PDF
+ documents can be used both for WWW presentation and printed copies.
+
+ The Isar proof language (see \chref{ch:proofs}) is embedded into the
+ theory language as a proper sub-language. Proof mode is entered by
+ stating some \hyperlink{command.theorem}{\mbox{\isa{\isacommand{theorem}}}} or \hyperlink{command.lemma}{\mbox{\isa{\isacommand{lemma}}}} at the theory
+ level, and left again with the final conclusion (e.g.\ via \hyperlink{command.qed}{\mbox{\isa{\isacommand{qed}}}}). Some theory specification mechanisms also require a proof,
+ such as \hyperlink{command.typedef}{\mbox{\isa{\isacommand{typedef}}}} in HOL, which demands non-emptiness of
+ the representing sets.%
