The Isabelle System DistributionVersion information This is the internal repository version of Isabelle. See the NEWS file in the distribution for details on user-relevant changes.System requirements Isabelle requires a regular Unix platform (e.g. GNU Linux) with the following additional software: * A full Standard ML Compiler (works best with Poly/ML 5.x). * The GNU bash shell (version 3.x or 2.x). * Perl (version 5.x). * GNU Emacs (version 21, 22) or XEmacs (version 21.4.x) -- for the Proof General interface. * A complete LaTeX installation -- for document preparation.Installation Binary packages are available for Isabelle/HOL and ZF for several platforms from the Isabelle web page. The system may be easily built from scratch as well, taking the traditional tar.gz source distribution. See file INSTALL as distributed with Isabelle for more information. Further background information may be found in the Isabelle System Manual, distributed with the sources (directory doc).User interface The canonical Isabelle user interface is Proof General by David Aspinall and others. It is a generic (X)Emacs interface for proof assistants, including Isabelle. Proof General is suitable for use by pacifists and Emacs militants alike. Its most prominent feature is script management, providing a metaphor of live proof script editing. Proof General is distributed together with the XEmacs X-Symbol package, which provides a reasonable way to get proper mathematical symbols displayed on screen.Other sources of information The Isabelle Page The Isabelle home page may be accessed both from Cambridge and Munich: * http://www.cl.cam.ac.uk/research/hvg/Isabelle/ * http://isabelle.in.tum.de Mailing list The electronic mailing list isabelle-users@cl.cam.ac.uk provides a forum for Isabelle users to discuss problems and exchange information.
