6 * Purpose : CGI-based actionsfile editor.
8 * NOTE: The CGIs in this file use parameter names
9 * such as "f" and "s" which are really *BAD* choices.
10 * However, I'm trying to save bytes in the
11 * edit-actions-list HTML page - the standard actions
12 * file generated a 550kbyte page, which is ridiculous.
14 * Stick to the short names in this file for consistency.
