About: http://dbpedia.org/resource/Camping_%28microframework%29

Camping is a web application framework which consistently stays at less than 4.5kb of code. The complete source code can be viewed on a single page. It is also available as a Ruby Gem. Camping stores a complete fledgling web application in a single file, like a bundle of many small CGIs scripts, but organizes it as a Model-View-Controller application as Ruby on Rails does. Camping applications can easily be ported to Rails.
