The current lineof Isabelle99 development introduces many new features, with only afew incompatibilities over Isabelle98-X. See the <tt>NEWS</tt> filein 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 main memory (somewhat depending on your MLsystem), with several tens of MB disk space and a decent CPU.Speaking by today's hardware standards, any moderate Linux box shouldmake a 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. SML of New Jersey).<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> SML/NJ 110.x on any Unix platform (e.g. Linux, Suns).<li> SML/NJ 0.93 on Suns and SGIs. There seem to be severalproblems with Linux and HP-UX, though.<li> Poly/ML versions 2.x and 3.1 on Suns.</ul><p><ahref="http://cm.bell-labs.com/cm/cs/what/smlnj/software.html">SML/NJ</a>needs lots of store and disk space, but it is free. The currentofficial release is 110 (there is an <ahref="ftp://ftp.cl.cam.ac.uk/MIRRORED/smlnj/release/110/smlnj-110.0-3.i386.rpm">RPMarchive</a> available for Linux/x86). We still support the old 0.93release, but do not recommend to use it.<p><a href="http://www.harlequin.com/products/ads/ml/">MLWorks</a> is acommercial ML programming environment. Isabelle on MLWorks 2.0 workswell. It is about 20% faster than on SML/NJ while using slightly lessmemory and disk space. A few minor features (e.g. ML top-level prettyprinting) are not yet supported, though.<p>Poly/ML used to be a commercial product by Abstract Hardware Limited(now Abstract, Inc.). It is no longer available. We're awaiting newsabout future availability of Poly/ML.<p><h2>Installation</h2>Binary rpm packages are available for Isabelle/HOL and ZF on theLinux/x86 platform. Alternatively, the system may be built fromscratch as described in file <tt>INSTALL</tt> of the Isabelle sources.Further background information may be found in the <em>Isabelle SystemManual</em>, distributed with the sources (directory <tt>doc</tt>).<h2>Interfaces</h2>The distribution includes only a very primitive interface based onordinary terminal sessions.<p><a href="http://www.dcs.ed.ac.uk/home/da/Isamode/">Isamode</a> byDavid Aspinall is a more elaborate interface for Isabelle. It runsunder recent versions of XEmacs and is useful to both novices andexperts.<p><a href="http://www.dcs.ed.ac.uk/home/proofgen/">Proof General</a> isa generic Emacs interface for proof assistants, including Isabelle(both for the classic and Isar version). Proof General is suitablefor use by pacifists and Emacs militants alike. Its most prominentfeature is script management, providing a metaphor of <em>live proofscript editing</em>.<h2>Other sources of information</h2><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.
