The Isabelle System Distribution
Version information
This is some unidentified repository version of Isabelle.
See the NEWS file in the distribution for details on user-relevant
changes.
System requirements
Isabelle requires a regular Unix-style platform (e.g. Linux,
Windows with Cygwin, Mac OS) and depends on the following main
add-on tools:
* The Poly/ML compiler and runtime system (version 5.2.1 or later).
* The GNU bash shell (version 3.x or 2.x).
* Perl (version 5.x).
* GNU Emacs (version 22) -- for the Proof General interface.
* A complete LaTeX installation -- for document preparation.
Installation
Completely integrated bundles including the full Isabelle sources,
documentation, add-on tools and precompiled logic images for
several platforms are available from the Isabelle web page.
Further background information may be found in the Isabelle System
Manual, distributed with the sources (directory doc).
User interface
The classic Isabelle user interface is Proof General by David
Aspinall and others. It is a generic Emacs interface for proof
assistants, including Isabelle. Its most prominent feature is
script management, providing a metaphor of stepwise proof script
editing. Proof General also provides some support for mathematical
symbols displayed on screen.
