We are looking to update our intranet with a content management system that provides wiki and forum support, as well as (hopefully) support for auto-generating content from files controlled under SVN such as Word documents. The aim is that we don't need to update the intranet each time a working practise changes and that we don't need to change the format of all our existing procedures to something more web-friendly.
I have already asked a question more specific to a particular CMS with no answers so far, but what I'd like to know is whether there is ANY CMS out there that can achieve what we'd like, free or otherwise?
