See the<tt>NEWS</tt> file in the distribution for details on user-relevantchanges.</p><h2>System requirements</h2><p>Isabelle requires a regular Unix platform (e.g. GNU Linux) with thefollowing additional software:</p><ul> <li>A full Standard ML Compiler (e.g. Poly/ML 4.1.x, SML/NJ 110.x).</li> <li>The GNU bash shell (version 2.x).</li> <li>Perl (version 5.x).</li> <li>XEmacs (version 21.4.x) -- for the ProofGeneral interface.</li> <li>A complete LaTeX installation (e.g. teTeX 1.0) -- for document preparation.</li></ul><h2>Installation</h2><p>Binary packages are available for Isabelle/HOL and ZF for severalplatforms from the Isabelle web page. The system may be easily builtfrom scratch as well, taking the traditional tar.gz sourcedistribution. See file <tt>INSTALL</tt> as distributed with Isabellefor more information.</p><p>Further background information may be found in the <em>Isabelle SystemManual</em>, distributed with the sources (directory <tt>doc</tt>).</p><h2>User interface</h2><p>The canonical Isabelle user interface is <ahref="http://proofgeneral.inf.ed.ac.uk/">Proof General</a> by David Aspinalland others. It is a generic (X)Emacs interface for proof assistants,including Isabelle (both for the classic and Isar version). ProofGeneral is suitable for use by pacifists and Emacs militantsalike. Its most prominent feature is script management, providing ametaphor of <em>live proof script editing</em>. Proof General hasrecently gained a rather large following of both beginning and expertusers of Isabelle.</p><p>Proof General is distributed together with the XEmacs<a href="http://x-symbol.sourceforge.net">X-Symbol package</a>, which provides a nice way to get propermathematical symbols displayed on screen.</p><h2>Other sources of information</h2><h3>The Isabelle Page</h3><p>The Isabelle home page may be accessed both from Cambridge and Munich:</p><ul> <li><a href="http://www.cl.cam.ac.uk/Research/HVG/Isabelle/">http://www.cl.cam.ac.uk/Research/HVG/Isabelle/</a></li> <li><a href="http://isabelle.in.tum.de">http://isabelle.in.tum.de</a></li></ul><h3>Mailing list</h3><p>The electronic mailing list <tt>isabelle-users@cl.cam.ac.uk</tt>provides a forum for Isabelle users to discuss problems and exchangeinformation.
