Introduction

JFLAP is a popular Java program for experimenting with finite state machines, 
Turing machines and other concepts from Formal Languages and Automata Theory. 
Version 7 of JFLAP can export JPG, PNG, GIF, BMP, or SVG images. JFLAP2TikZ is 
a groovy script that converts a JFLAP jff file representing a finite automaton, 
pushdown automaton, or Turing machine into a LaTeX file depicting the automaton 
graphically using TikZ.

Requirements

To use JFLAP2TikZ you will need Java installed. Additionally, you may find it 
useful to have Groovy installed as well. You will need to download either 
jflap2tikz.jar (if you only have Java installed) or jflap2tikz.groovy (if you 
also have groovy installed).

Usage

JFLAP2TikZ is invoked from the command line with:

java -jar jflap2tikz.jar -i example.jff

or:

groovy jflap2tikz.groovy -i example.jff

In the above cases the output will be written to the console. Use the -h option 
to see the full usage information, which is also given below.

usage: jflap2tikz [options]
Version 1.1
 -d,--accepting-distance <distance>   Distance, in pt, between the circles of an
                                      accepting state (default is 2)
 -g,--grid <size>                     Round positions so that they are on a
                                      grid. If a size is given it sets the
                                      spacing of the grid (default is 20.0)
 -h,--help                            Show usage information and quit
 -i,--input-file <filename>           Name of a JFLAP jff file representing a
                                      finite automaton, pushdown automaton, or
                                      Turing machine. If a file is not given
                                      standard input will be used.
 -l,--arrow-length <length>           Length of arrows in points (default is 9)
 -o,--output-file <filename>          Name of a file for writing output. If this
                                      file already exists it will be
                                      overwritten.
 -r,--rotate                          Rotate labels along edges
 -s,--scale <x>                       1 pixel in JFLAP = x points in LaTeX
                                      (default is 1.0)
 -w,--arrow-width <width>             Width of arrows in points (default is 6)
