From the VSL newsletter:
We're happy and proud to announce five new web sites that we have put online, featuring our five areas of software development. While we started to work on a redesign of our main web site, we wanted to share some ideas with you, giving you the benefit of finding information about each software product under its respective URL.
Very nice design... and it functions like a normal site. Finally. Thank you for your attention to web standards so that all browsers work as they should.
