[Plugin: WP Calendar] URL rewriting

Hello,

I’m using v1.4.3 and the url are generated as this :

http://www.domain.com/detail-agenda?event=1055 (it’s in french because the site is in french)

I would like to rewrite these URL to have ones with the event title in order to improve search engine ranking.

What have I to do ? Please avoid to tell me to update de plugin, I want to avoid that.

Thank you

Best regards
