We move the "_Thanks for the help_" out from under the "Entries" menu and under the "About" menu to better balance the menus. Besides, "_Thanks for the help_" is more **about** the IOCCC itself.

Judges' remarks:
See the author's POSIX P1003.2-like documentation file ant.txt for more information.
This program demonstrates that POSIX doesn't guarantee readability. :-)
Author's remarks:
Some of the features of my entry are:
- "Lengthy" POSIX.2 style specification and manual :) :)
- Useful subset of POSIX.2 Extended Regular Expressions.
- Recursive ERE parser/compiler that generates an NFA railroad.
- Lazy NFA to DFA evaluation to improve performance speed.
- Code tested on a variety of platforms.
- Make driven test script.
- Can be compiled with ANSI or K&R C.
- Not a toy, but actually useful and usable on systems that use DOS.
