-<h2>Proof-by-pointing support for Isabelle</h2>
-<p>
-Isabelle has a sophisticated concrete syntax mechanism which makes it
-difficult to add annotations to connect the displayed output back to
-the internal abstract syntax. This issue needs to be solved to
-support proof-by-pointing (and other features) in Isabelle.
-A
-<a href="http://www.informatik.uni-bremen.de/~bu/isa_contrib/isabelle.html">
-patch by Burkhart Wolff</a>
-providing term structure annotations for a previous release of
-Isabelle may be useful here. To implement proof-by-pointing itself,
-tactics using the gesture information must be written.
-</p>
-<p>
-<b>Skills:</b>
- Some understanding of Isabelle implementation,
- co-operation with the Isabelle developers to get
- Isabelle modifications incorporated.
- Skill in writing Isabelle tactics.
- Minimal Emacs Lisp knowledge.
