This is the Version 3.0 of the theorem prover SETHEO.


0. If you have not already done this, please send the file 
   SETHEO.user.registration by e-mail to 
   setheo@informatik.tu-muenchen.de .
   After that you will be registred as a SETHEO user and you will
   automatically be informed about new developments regarding SETHEO.


1. The following binaries for Sun SparcStations (!!) are in this package:
	(subdirectory `bin.sun4')

setheo		a top-level shell-script to run the prover with
		a default set of options. It should be used by novice
		users.

xsetheo		a X-window based graphical user interface to
		run the theorem prover, display the proof-tree
		in a graphical way, and to modify the formula.

xsetheo.dyn	is the same as xsetheo, but with a dynamic linkage 
		of the libraries. For details see below.

clop		a command to compile the input formula.

sam		the prover itself (the SETHEO Abstract Machine).

xptree		the X-window based display of the proof-tree.

inwasm		this is the actual compiler which generates
		assembler code.

wasm		this is the assembler which takes assembly code
		and produces binary code for the sam.


2. Installation

All binaries should be placed in one directory.
The default directory is "/home/setheo/bin.sun4".
If the binaries are to be placed in a different directory,
the shell-variable SETHEOHOME is to be set to the appropriate
value, e.g. (c-shell)

setenv SETHEOHOME /usr/local/pub/bin

The following programs need this variable: setheo,clop,xsetheo

Two versions of the graphical user-interface are provided:
xsetheo with a static binding of the X-library.

xsetheo.dyn with dynamic binding of all libraries.

Depending on the installation of X (or Openwindows) you have to try
which version runs.


3. Manual Pages

Manual pages are present for all binaries in this package and are
located in the directory `manpages'.


4. Input Language Description

A formal description of the input language is given in the file
`lop.syntax' in the directory `manpages'.


5. Example Problems

The directory `examples' contains a small selection of problems
in LOP syntax, i.e. the input syntax of SETHEO.
In order to test your installation, just type
	`` setheo <problem> ''
where <problem>.lop is the name of an example problem.
The file <problem>.out contains the output of a proof of 
<problem> with certain SETHEO switches.


6. Sources

The sources of the SETHEO system are available on request.
In this case, please send an e-mail to
      setheo@informatik.tu-muenchen.de

The sources then will be sent to you via e-mail free of charge.

The sources are also available on QIC-11 or QIC-24 type streamer tape.
For the cartridge and administrative costs, US$ 100 will be charged.
