<title>The Isabelle System Distribution</title>


<h1>The Isabelle System Distribution</h1>

<h2>Version information</h2>

This is the internal repository version of Isabelle.  The current line
of Isabelle99 development introduces many new concepts, while
attempting to keep incompatibilities over Isabelle98 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. Fun
starts at about 32-64 MB of free main memory (somewhat depending on
the ML system), with several tens of MB disk space and a decent CPU.
Speaking by today's hardware standards, any moderate Linux box should
give a very nice platform for Isabelle.


Furthermore, Isabelle needs the following software, which is not part
of the distribution:
<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.x
is <em>not</em> sufficient).


The following ML system and platform combinations are known to work
very well:
<li> Poly/ML 4.x and 3.x on Linux/x86 and Solaris/Sparc.
<li> SML/NJ 110.x on any Unix platform (Linux, Suns, SGI etc.).

<p> <a href="">Poly/ML</a>, previously a
commercial product, is back in the free world.  It is by far the best
compiler for running Isabelle, requiring the least memory and offering
the highest performance.

<p> <a
needs lots of store and disk space, but supports many more platforms.
The current official release is 110.  Basically, we still support the
old 0.93 release, but do not recommend to use it under normal

<p> MLWorks is a commercial ML programming environment developed by <a
href="">Harlequin</a> and was unfortunately
withdrawn after that company was taken over.  Isabelle on MLWorks 2.0
works reasonably well.


Binary packages are available for Isabelle/HOL and ZF on the Linux/x86
platform.  The system may be easily built from scratch as well, taking
the traditional tar.gz source distribution.  See file <tt>INSTALL</tt>
as distributed with Isabelle for more information.

Further background information may be found in the <em>Isabelle System
Manual</em>, distributed with the sources (directory <tt>doc</tt>).

<h2>User interface</h2>

The canonical Isabelle user interface is <a
href="">Proof General</a> 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 <em>live proof script editing</em>.  Proof General has
recently gained a rather large following of both beginning and expert
users of Isabelle.


Proof General may be used together with the Emacs
<a href="">
X-Symbol package</a>, which provides a nice way to get proper
mathematical symbols displayed on screen.

helpful, we can accept no responsibility for the deficiencies of
Isabelle and their consequences.
