I took this one-page PHP script from a forum with no attribution. I altered the parsing of wiki words so that it would convert more urls into working links.<br /><br />First character is space, this is monospaced.<br />four dashes give you a horizontal rule.<br />first char is dash, then space, the line is a bulleted list.<br />wiki page links are marked with a tilde as the first character. Just make sure you only use characters in the link that are legal for filenames.
