It is inspired by a similar framework written by Arnór Heiðar Sigurðsson. In the same spirit but more advanced and more complete, see also nanoc - in Ruby.
sview is designed to organize essentially static websites. It does not offer the features you would expect from a complete MVC framework - actually, it has only the "V" part. If you want a more demanding dynamic website, consider using an appropriate tool, Symfony for example.
The archive sample-website.tar.xz provides a basic but full website example. Complementarily, the file HOWTO.html gives some details about sview usage.
