3 * The Paper Tape Project -- Documentation
4 *
5 * This is a very small "template" like system that quickly wraps a design around any
6 * *.htm file in the Paper-Tape-Project repository. It should handle links, etc.
7 * well and works with PATH_INFO, typical calls are ".../index.php/path/to/file.htm".
8 * There's a small menu nested as PHP array in this script.
9 *
10 * Use this small script as in the public domain.
