     1 		     ISABELLE-93 DISTRIBUTION DIRECTORY
     2 
     3 ------------------------------------------------------------------------------
     4 ISABELLE-93 IS INCOMPATIBLE WITH EARLIER VERSIONS.  PLEASE CONSULT THE
     5 DOCUMENTATION.

     8 This directory contains the complete Isabelle system.  To build and test the
     9 entire system, including all object-logics, use the shell script make-all.
    10 Pure Isabelle and each of the object-logics can be built separately using the
    11 Makefiles in the respective directories; read them for more information.
    12 
    13 				THE MAKEFILES
    14 
    15 The Makefiles can use two different Standard ML compilers: Poly/ML version
    16 2.03 or later (from Abstract Hardware Ltd) and Standard ML of New Jersey
    17 (Version 0.93 or later).  Poly/ML is a commercial product and costs money,
    18 but it is reliable and its database system is convenient for interactive
    19 work.  SML of New Jersey requires lots of memory and disc space, but it is
    20 free and its code sometimes runs faster.  Both compilers are perfectly
    21 satisfactory for running Isabelle.
    22 
    23 The Makefiles and make-all use enviroment variables that you should set
    24 according to your site configuration.
    25 
    26 ISABELLEBIN is the directory to hold Poly/ML databases or New Jersey ML
    27 images.  When using Poly/ML, ISABELLEBIN must be an absolute pathname (one
    28 starting with "/").
    29 
    30 ML_DBASE is an absolute pathname to the initial Poly/ML database (not
    31 required for New Jersey ML).
    32 
    33 ISABELLECOMP is the ML compiler, typically "poly -noDisplay" or "sml".  If
    34 ISABELLECOMP begins with the letters "poly" then the Makefiles assume that
    35 it is Poly/ML; if it begins with the letters "sml" then they assume
    36 Standard ML of New Jersey.  
    37 
    38 If a Poly/ML session fails with the message "Run out of store" then you
    39 have used up the entire heap.  If your tactic is not in a loop, allocating
    40 more heap at startup should correct the problem.  For instance, "poly -h
    41 15000" allocates sufficient heap space to rebuild all Isabelle examples.
    42

    44 			 STRUCTURE OF THIS DIRECTORY
    45 
    46 The directory Pure containes pure Isabelle, which has no object-logic.
    47 
    48 Other important files include...
    49   COPYRIGHT   		Copyright notice and Disclaimer of Warranty
    50   make-all		shell script for building entire system
    51   expandshort		shell script to expand "shortcuts" in files
    52   prove_goal.el       	Emacs command to change proof format
    53   xlisten		shell script for running Isabelle under X
    54   teeinput		shell script to run Isabelle, logging inputs to a file
    55   Pure			directory of source files for Pure Isabelle
    56   Provers		directory of generic theorem provers
    57 
    58 xlisten sets up a window running Isabelle, with a separate small "listener"
    59 window, which keeps a log of all input lines.  This log is a useful record
    60 of a session.  If you are not running X windows, teeinput can still be used at
    61 least to record (if not to display) the log.
    62 
    63 The following subdirectories contain object-logics:
    64   FOL 	  Natural deduction First-Order Logic (intuitionistic and classical)
    65   FOLP 	  First-Order Logic with Proof terms
    66   ZF	  Zermelo-Fraenkel set theory
    67   CTT	  Constructive Type Theory
    68   HOL	  Classical Higher-Order Logic
    69   LK	  Classical first-order sequent calculus
    70   Modal	  The modal logics T, S4, S43
    71   LCF     Logic for Computable Functions (domain theory)
    72   CCL	  Martin Coen's Classical Computational Logic
    73   Cube	  Barendregt's Lambda Cube
    74 
    75 Object-logics include examples files in subdirectory ex or file ex.ML.
    76 These files can be loaded in batch mode.  The commands can also be
    77 executed interactively, using the windows on your workstation.  This is a
    78 good way to get started.
    79 
    80 Each object-logic is built on top of Pure Isabelle, and possibly on top of
    81 another object logic (like FOL or LK).  A database or binary called Pure is
    82 first created, then the object-logic is loaded on top.  Poly/ML extends
    83 Pure using its "make_database" operation.  Standard ML of New Jersey starts
    84 with the Pure core image and loads the object-logic's ROOT.ML.

    86 		HOW TO GET A STANDARD ML COMPILER
    87 
    88 To obtain Poly/ML, contact Mike Crawley <mjc@ahl.co.uk> at Abstract
    89 Hardware Ltd, The Howell Building, Brunel University, Uxbridge UB8 3PH,
    90 England.
    91 
    92 To obtain Standard ML of New Jersey, contact David MacQueen
    93 <dbm@com.att.research> at AT&T Bell Laboratories, 600 Mountain Avenue,
    94 Murray Hill, NJ 07974, USA.  This compiler is available by FTP.  Connect to
    95 research.att.com; login as anonymous with your userid as password; set
    96 binary mode; transfer files from the directory dist/ml.

   101 we can accept no responsibility for the deficiences of Isabelle amd their
   102 consequences.
