HybridSal Abstractor.
----------------------

Requirements: The following is required to run hybridsal---
-------------

1.  Lisp runtime. 
    HybridSal abstractor was developed using Allegro Common Lisp.
    It has not been tested on other Lisp compilers/interpreters.
    It also requires net.xml.parser which comes with Allegro Common Lisp.
    (I will soon test it on CMU Lisp).
   
2.  Java runtime and antlr-2.7.1 jar files.
    The hybridsal2xml parser requires java and antlr-2.7.1 jar files.
    Read the README file in the directory hybridsal2xml for more
    information.


Installation:
-------------
1. Install hybridsal2xml.
   cd hybridsal2xml 
   and follow the instructions in the 
   README file in that subdirectory.


Testing:
--------
Test your installation by running
  make test
from the command-line.
This will first create abstractions of
FIVE models, and then model-check the
abstractions using the SAL symbolic
model checker.  YOU NEED to have SAL
(sal-smc) installed for running the tests.



Running:
---------
To run the hybridsal abstractor, start lisp,
load the file "load.lisp".
If successful, you should use the commands,
as illustrated in load-test.lisp, to create
abstractions of HybridSAL models.

Before using hybridsal abstractor, go through the
two examples given in the examples subdirectory.
See the examples/README file for details.

Bug fixes:
----------
03.05.09: Booleans were only supported as boolvar=TRUE.
 Now we also support (boolvar). 

03.05.09: Circularity in class-definitions eliminated.
