style/jakarta-maven.css

Hi folks,

while updating the Jakarta site for the HttpComponents move,
I noticed that somebody had modified jakarta-maven.css on
the server directly, instead of changing the contents in SVN
and checking it out. The change was to replace the ad for
ApacheCon 2007 with the one for ApacheCon 2008. A good idea
to update that, but I recommend to use the established
procedures for updating our website. It's fixed now.

cheers,
Roland
