The current lineof development introduces many new features, while attempting to keepincompatibilities over Isabelle98-X at a minimum. See the<tt>NEWS</tt> file in the distribution for more details.<h2>System requirements</h2>Isabelle requires a real Unix box with sufficient resources. Funstarts at about 32-64 MB of free main memory (somewhat depending onyour ML system), with several tens of MB disk space and a decent CPU.Speaking by today's hardware standards, any moderate Linux box shouldgive a very nice platform for Isabelle.<p>Furthermore, Isabelle needs the following software, which is not partof the distribution:<ul><li> A full Standard ML Compiler (e.g. Poly/ML).<li> The GNU bash shell (version 1.x or 2.x).<li> Perl 5.x - the Pathologically Eclectic Rubbish Lister (Perl 4.xis <em>not</em> sufficient).</ul><p>The following ML system and platform combinations are known to workvery well:<ul><li> Poly/ML 3.x on Linux and Sparc/Solaris.<li> SML/NJ 110.x on any Unix platform (Linux, Suns, SGI etc.).<li> SML/NJ 0.93 on Suns and SGIs. There seem to be severalproblems with Linux and HP-UX, though.</ul><p> <a href="http://www.polyml.org/">Poly/ML</a>, previously acommercial product, is back in the free world. It is by far the bestcompiler for running Isabelle, requiring the least memory and offeringthe highest performance.<p> <ahref="http://cm.bell-labs.com/cm/cs/what/smlnj/software.html">SML/NJ</a>needs lots of store and disk space, but supports many more platforms.The current official release is 110. Basically, we still support theold 0.93 release, but do not recommend it.<p> MLWorks is a commercial ML programming environment developed by <ahref="http://www.harlequin.com/">Harlequin</a> and was unfortunatelywithdrawn after that company was taken over. Isabelle on MLWorks 2.0works well. It is about 20% faster than on SML/NJ while usingslightly less memory and disk space. A few minor features (e.g. MLtop-level pretty printing) are not supported, though.<h2>Installation</h2>RPM packages are available for Isabelle/HOL and ZF on the Linux/x86platform. The system may be easily built from scratch as well, takingthe traditional tar.gz distribution. See file <tt>INSTALL</tt> asdistributed with Isabelle for more information.Further background information may be found in the <em>Isabelle SystemManual</em>, distributed with the sources (directory <tt>doc</tt>).<h2>User interfaces</h2>The distribution includes only a very primitive interface based onordinary terminal sessions. Advanced interfaces are available fromother sources:<ul><li><a href="http://www.dcs.ed.ac.uk/home/proofgen/">Proof General</a> byDavid Aspinall and others is a generic Emacs interface for proofassistants, including Isabelle (both for the classic and Isarversion). Proof General is suitable for use by pacifists and Emacsmilitants alike. Its most prominent feature is script management,providing a metaphor of <em>live proof script editing</em>. ProofGeneral has recently gained a rather large following of both beginningand expert users of Isabelle.<li><a href="http://www.dcs.ed.ac.uk/home/da/Isamode/">Isamode</a> byDavid Aspinall is an older and simpler Emacs interface for Isabelle.It runs under recent versions of XEmacs.</ul><h2>Other sources of information</h2><h3>The Isabelle Page</h3>The Isabelle home page may be accessed both from Cambridge and Munich:<ul><li> <ahref="http://www.cl.cam.ac.uk/Research/HVG/Isabelle/">http://www.cl.cam.ac.uk/Research/HVG/Isabelle/</a><li> <a href="http://isabelle.in.tum.de">http://isabelle.in.tum.de</a></ul><h3>Mailing list</h3>The electronic mailing list <tt>isabelle-users@cl.cam.ac.uk</tt>provides a forum for Isabelle users to discuss problems and exchangeinformation.
