My model checker is a command line tool so I was basically interesting
in using the part of dracula that interfaces with ACL, without using
GUI stuff.

I can easily generate the lisp file, so after that I will look into
the automation then. Thanks for the suggestion.
I will look into ACL2 page to check out which parts of lisp I can use then.
