Interesting. In general: What would be the best approach towards having a part of the website static (main part), and only the blog/press part being regenerated? Does Hugo/Pelican/Jekyll/Hakyll etc handle this kind of functionality? As an alternative, what would be a good light weight CMS these days (ideally in Python)?
