\begin{abstract}
  Isar offers a high-level proof (and theory) language for Isabelle.
  We give various examples of Isabelle/Isar proof developments,
  ranging from simple demonstrations of certain language features to a
  bit more advanced applications.  The ``real'' applications of
  Isabelle/Isar are found elsewhere.
