Limonade is a PHP micro framework for rapid web development and prototyping.

It's inspired by frameworks like Sinatra or Camping in Ruby, or Orbit in Lua. It aims to be simple, lightweight and extremly flexible.

Limonade provides functions that complete the PHP basic set, while keeping consistency with native functions and sitting up on them.Limonade is easy to learn and provides everything that you can expect from a modern framework (MVC, REST)
