- * Title: DOM Tooltip Library
- * Version: 0.7.3
- *
- * Summary:
- * Allows developers to add custom tooltips to the webpages. Tooltips are
- * generated using the domTT_activate() function and customized by setting
- * a handful of options.
- *
- * Maintainer: Dan Allen <dan.allen@mojavelinux.com>
- * Contributors:
- * Josh Gross <josh@jportalhome.com>
- * Jason Rust <jason@rustyparts.com>

- * However, if you use this library, you earn the position of official bug
- * reporter :) Please post questions or problem reports to the newsgroup:
- *
- * http://groups-beta.google.com/group/dom-tooltip
- *
- * If you are doing this for commercial work, perhaps you could send me a few
- * Starbucks Coffee gift dollars or PayPal bucks to encourage future
- * developement (NOT REQUIRED). E-mail me for my snail mail address.
