Compared tothe Isabelle94 line it introduces many new features, but also someimcompatibilities. See the <tt>NEWS</tt> file in the distribution formore details.<h2>System requirements</h2>Isabelle requires a real Unix box with sufficient resources. Funstarts at about 32MB of memory (somewhat depending on your ML system),with several tens of MB disk space and a relatively fast CPU.<p>Furthermore, it needs the following software, which is not part of thedistribution:<ul><li> A full Standard ML Compiler (e.g. Poly/ML or SML of New Jersey).<li> The GNU bash shell (version 1.x or 2.x).<li> Perl 5.x - the Pathologically Eclectic Rubbish Lister.</ul><p>The following ML system and platform combinations are known to workquite well:<ul><li> Poly/ML versions 2.x and 3.1 on Suns.<li> SML/NJ 0.93 on Suns and SGIs. There seem to be severalproblems with Linux and HP-UX.<li> SML/NJ versions 109.27 to 109.33 on Suns, Linux, etc.<li> SML/NJ 110 on Suns, Linux, etc.</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. We also still support the old 0.93 releaseand working versions 109.27 to 109.33. Support for the 109 line ofSML/NJ will be dropped next time!<p><a href="http://www.ahl.co.uk/poly-ml.html">Poly/ML</a> is acommercial product and costs money, but it is stable and efficient. Itrequires relatively little memory (starting at about 16MB) and diskspace (about 40MB for all distributed object logics).<p><a href="http://www.harlequin.com/products/ads/ml/">MLWorks</a> is acommercial ML programming environment. Isabelle on MLWorks should bestill considered experimental!<p><h2>Installation</h2>See file <tt>INSTALL</tt> in the Isabelle sources on how to build thesystem. Further background information may be found in the<em>Isabelle System Manual</em>, distributed as <tt>dvi</tt> with thesources.<h2>Interfaces</h2>The distribution includes only a very primitive interface based onordinary terminal sessions.<p>David Aspinall has written a more elaborate <ahref="ftp://ftp.dcs.ed.ac.uk/pub/da/Isamode.tar.gz">user interface</a>for Isabelle. It runs under recent versions of GNU Emacs and XEmacs,the latter being recommended. It's useful to both novices andexperts.<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.
