 Isabelle Packages

 %body%

 <p>

 The following source and binary packages of <!-- _GP_ distname -->

 provide everything required for easy installation of the full Isabelle

 working environment on common Unix platforms.

 <p>

 A <em>minimal</em> Isabelle installation requires only <tt>bash</tt>

 and <tt>perl</tt> (usually provided by the operating system), and a

 suitable implementation of Standard ML (e.g. <a

 href="http://www.polyml.org">Poly/ML</a> as provided below).  A

 <em>comfortable</em> Isabelle working environment demands further user

 interface support, as provided by <a

 href="http://www.proofgeneral.org">Proof General</a> together with the

 (optional) <a

 href="http://www.fmi.uni-passau.de/~wedler/x-symbol/">X-Symbol</a>

 package.  Both of these should be used with a recent version of <a

 href="http://www.xemacs.org">XEmacs-21</a>.

 <p>

 <h2>Packages</h2>

 We provide a complete set of packages for Isabelle, Proof General and

 X-Symbol.  While XEmacs-21 is not included here, most operating system

 distributions already provide a suitable package, although not

 installed by default.

 <p>

 Some packages are platform dependent.  Everything is included below

 for Linux/x86 and Solaris/Sparc systems.  Other Unix platforms work as

 well, but require manual compilation of Isabelle logic images using a

 suitable Standard ML system.

 <h2>Installation</h2>

 Installation is very easy.  Basically, just unpack all required

 packages within the same directory.  There is <em>no</em> manual

 configuration required of any of these components, if used according

 the default settings of Isabelle.

 <p>

 A typical Linux/x86 site installation of Isabelle/HOL works as

 follows.  By using GNU <tt>tar</tt>, the archives are uncompressed and

 unpacked into the <tt>/usr/local</tt> directory (this location may be

 changed to anything appropriate).

 <p>

 <tt>

    tar -C /usr/local -xzf

 <!-- _GP_ href(distname . ".tar.gz", distname . ".tar.gz") --> <br>

    tar -C /usr/local -xzf

 <!-- _GP_ href("contrib/polyml_base.tar.gz", "polyml_base.tar.gz") --> <br>

    tar -C /usr/local -xzf

 <!-- _GP_ href("contrib/polyml_x86-linux.tar.gz", "polyml_x86-linux.tar.gz") --> <br>

    tar -C /usr/local -xzf

 <!-- _GP_ href("HOL_x86-linux.tar.gz", "HOL_x86-linux.tar.gz") --> <br>

    tar -C /usr/local -xzf

 <!-- _GP_ href("contrib/ProofGeneral.tar.gz", "ProofGeneral.tar.gz") --> <br>

    tar -C /usr/local -xzf

 <!-- _GP_ href("contrib/x-symbol.tar.gz", "x-symbol.tar.gz") --> <br>

 </tt>

 <p>

 The installation may be finished as follows:

 <p>

 <tt>

 &nbsp;&nbsp; <!-- _GP_ "cd /usr/local/" . distname --> <br>

 &nbsp;&nbsp; ./configure <br>

 &nbsp;&nbsp; ./bin/isatool install -p /usr/local/bin <br>

 </tt>

 <p>

 Users can now invoke the Isabelle executables without further ado,

 e.g. just start the main <tt>Isabelle</tt> executable to lauch the

 Isabelle Proof General interface.
