LTL3 tools README
-=-=-=-=-=-=-=-=-

What you need to properly use the LTL3 tools:
---------------------------------------------

Download:

  1. AT&T's fsmlibrary version 4.0. It used to be widely available under
     a free-to-use license for noncommercial purposes, but now seems to
     be available only upon request.  Perhaps, these folks can help:

     https://github.com/att

     Otherwise use a web search, as many universities still use the library
     in their courses and offer binaries to download.

  2. LTL2BA: http://www.lsv.ens-cachan.fr/~gastin/ltl2ba/
     (tested with version 1.1 of the translator)

  3. Optional: AT&T's Graphviz, which includes the programs dot, dotty,
     etc.  Note that most modern Linux systems have these preinstalled.

Then simply copy the binaries of 1. and 2. into the third-party/ directory
of the LTL3 tools distribution.  (2. may have to be compiled first.)

How to run ltl2mon / the LTL3 tools:
------------------------------------

  1. Change into the directory where you extracted the package

  2. Optional: Check the settings inside ltl2mon
     (ltl2mon is the main entry point to the LTL3 tools)

  3. Run, for example, "./ltl2mon "(! a) U b" | dot -Tps > graph.ps"

How to compile the LTL3 tools:
------------------------------

If you are on i686 GNU/Linux, you do not have to compile the LTL3
tools as there are some statically linked binaries in the bin/
directory.  Otherwise, follow these steps to compile the LTL3 tools:

  1. Change into the directory where you extracted the package
  
  2. Run "make install"

     Notice, ltl2mon is written in Ocaml.  So, you will need an Ocaml
     tool chain.
