-Webby is a super fantastic little website management system. It would be called a _content management system_ if it were a bigger kid. But, it's just a runt with a special knack for transforming text. And that's really all it does - manages the legwork of turning text into something else, an *ASCII Alchemist* if you will.

-Webby works by combining the contents of a *page* with a *layout* to produce HTML. The layout contains everything common to all the pages - HTML headers, navigation menu, footer, etc. - and the page contains just the information for that page. You can use your favorite markup language to write your pages; Webby supports quite a few.

-Webby has a great _autobuild_ feature that continuously generates HTML whenever the *pages* or *layouts* change. The HTML is served up via {heel}[http://copiousfreetime.rubyforge.org/heel/], a static file webserver based on mongrel. Whenever you change a page, you can immediately see those changes without having to run any commands.
