Alternative open source CMS to PostNuke and PHPNUKE?

[temi]

Hello,
Does anyone know a robust open source CMS software that is also search engine friendly ?

Thanks

I know these alternatives:
http://ez.no ezPublish
http://plone.org Plone CMS
also the Horde framework deserves quite a bit of attention.

However I don't know it these alternatives work with search-engine friendly URLs...
