Handler Problems to Overcome" ?> In order to create a system that is fast and easy to use that doesn't surprise the user, we had a few problems to solve:

1. Keep each page 'seperate' - if you set a variable in foo.rvt, you don't want to see it again in bar.rvt.
2. Provide a way to share global data for those who need to access it. Persistent database connections, or sockets, for example.
3. Provide clean integration of Tcl and HTML, in order to make quick and dirty templating possible, and easy.
4. Let users use 'normal' Tcl scripts. One of the big advantages Tcl has (over, say, PHP) is that it is a multi-purpose language. It's not restricted to just the web. Rivet attempts to make it possible to take ordinary Tcl code and run it in Rivet without changes, which means there is more code available to use.
5. Keep the whole system fast!
