<title>The Isabelle System Distribution</title>


<h1>The Isabelle System Distribution</h1>

<h2>Version information</h2>

This is the internal repository version of Isabelle.  See the
<tt>NEWS</tt> file in the distribution for details on user-relevant

<h2>System requirements</h2>

Isabelle requires a real Unix box with sufficient resources, say 64 MB
of free main memory and a decent CPU.  Speaking by today's hardware
standards, any moderate Linux box should give a very nice platform for


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, Solaris/Sparc, and PowerPC platforms.
<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 used to be 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unfortunately withdrawn after that company was taken over.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.

Isabelle and their consequences.
