Regular Expression Graphing Program project is a regular expression graphing program.

This program is designed to take a regular expression and produce a graph of the state machine that is used to parse the regular expression.

It is useful for teaching regular expressions and state machines.

The program comes with a built-in tutorial and sample set of regular expressions.

Here are some key features of "Regular Expression Graphing Program":
This will not graph all the regular expressions. Some of the more advanced features of the engine are just not handled.
We currently ``graph'' the ``group, no $1'' (?:..) operator by displaying nothing. A box should be put around the expression.
The boxes drawn by the program are a fixed with not related to the size of the text they contain. Text can easily overflow the box.
The system is UNIX/Linux specific. This is caused by only one small section of code should anyone want to port this to a braindamaged operating system.
Better use of color can be made. Specifically all the nodes do not have to be green. Come to think of it they call don't have to be rectangles either.
Sometimes the lines connecting one section to another take some strange twists.
