5 * A configurator intended to read it's config from a PHP-style INI file,
6 * instead of a PHP file.
8 * Pass a filename to the IniConfig() function and it will read all it's
9 * definitions from there, all by itself, and proceed to do a mass-define
10 * of all valid PHPWiki config items. In this way, we can hopefully be
11 * totally backwards-compatible with the old index.php method, while still
12 * providing a much tastier on-going experience.

37 * - Convert the value lists to provide defaults, so that every "if
38 * (defined())" and "if (!defined())" can fuck off to the dismal hole
41 * - Resurrect the larger "config object" code (in config/) so it'll aid the
42 * GUI config writers, and allow us to do proper validation and default
45 * - Get rid of WikiNameRegexp and KeywordLinkRegexp as globals by finding
46 * everywhere that uses them as variables and modify the code to use
47 * them as constants. Will involve hacking around
48 * pcre_fix_posix_classes (probably with redefines()).
