[Catalyst] create search engine friendly uri from string

[Moritz Onken]

Hi,

I was wondering if anyone has a nice regex or module which modifies a  
string to look good in an url.
You know this behaviour from blogs which make urls from the blog title

Example: "Beta Launch Invites: Kwyno Brings The Web Into Your IM And  
(Soon) SMS Inboxes" -> http://www.techcrunch.com/2008/12/15/beta-launch-invites-kwyno-brings-the-web-into-your-im-and-soon-sms-inboxes/

Any ideas?

cheers,

moritz
