                       The Isabelle System Distribution

Version 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 (e.g. Poly/ML 5.x, 4.x).
     * The GNU bash shell (version 3.x, 2.x).
     * Perl (version 5.x).
     * XEmacs (version 21.4.x) -- for the ProofGeneral 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 [1]Proof General by David
   Aspinall and others. It is a generic (X)Emacs interface for proof
   assistants, including Isabelle (both for the classic and Isar
   version). 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 has
   recently gained a rather large following of both beginning and expert
   users of Isabelle.

   Proof General is distributed together with the XEmacs [2]X-Symbol
   package, which provides a nice way to get proper mathematical symbols
   displayed on screen.
