- * Rewritten by Nathan Codding - Feb 6, 2001.

- * - Goes through the given string, and replaces xxxx://yyyy with an HTML <a> tag linking

- * to that URL

- * - Goes through the given string, and replaces www.xxxx.yyyy[zzzz] with an HTML <a> tag linking

- * to http://www.xxxx.yyyy[/zzzz]

- * - Goes through the given string, and replaces xxxx@yyyy with an HTML mailto: tag linking

- * to that email address

- * - Only matches these 2 patterns either after a space, or at the beginning of a line

- *

- * Notes: the email one might get annoying - it's easy to make it more restrictive, though.. maybe

- * have it require something like xxxx@yyyy.zzzz or such. We'll see.
