Regex expression tester.

    I know that there exist in Perl, TCL and Lisp programs for testing regular
    expressions.

    These testers, you give the tester a string, type in some regex. As the
    regex is entered it will show the string, highlighting the part that
    matches. It is used for programmers in those language to
    design their regex.

    Of course one can take a regex made in one tester and use it in any
    language. But my experience is that in almost any language, if you
    construct a regex, it's better to do it using the same regex machine that
    will be used when the program is run. Each engine has it's own little
    idiosyncrancies. So it's better to use the same machine to test a regex
    that it will be used with.

    Is there some program that allowqs one to do this?
