''void **addPath** (string **path type**, string **directory**)''Adds a directory to the list of paths Text_Wiki searches for user-defined parse and render classes.<code php>

$wiki =& new Text_Wiki();

// add a user-defined "parse" path
$wiki->addPath('parse', '/path/to/parse/rules/');

// add a user-defined "render" path
$wiki->addPath('parse', '/path/to/render/classes/');
</code>Text_Wiki searches these paths in last-in-first-out order; that is, paths are added to the "top" of the search stack.  For example, if the default render search stack is ...
  - ''/original/path/''... and you call ''addPath('render', '/path/to/custom/renders/')'', the search stack will then look like this:
  - ''/path/to/custom/renders/''
  - ''/original/path/''The ''/path/to/custom/renders/'' will be searched first, then fall back to ''/original/path/''.
