New XBeach website

[dano]

Dear XBeach user,

As of today the google groups website will be closed, as it had become
increasingly cranky. All XBeach stuff, downloads, discussions etc can
now be found at Deltares'open source softeware site:

http://oss.deltares.nl/web/xbeach/

Here we have merged all information from the Wiki, the previous
website and the discussion group. If this is the first time you get
there, please register under 'getting started' or go directly to

http://oss.deltares.nl/web/xbeach/register

Best regards,

Dano Roelvink
