Rapicorn is an experimental graphical user interface toolkit. Many things that programmers need to spell out explicitely in other toolkits are automated in Rapicorn and duplicate manual work is reduced as much as possible. It aims at bringing UI-design, UI-notation and UI-programming as close together as possible. This is accomplished by providing conscise ways for user interface notation and providing a simple to use programming interface.

This tutorial focuses on the presentation of Rapicorn's programming interface and guides through creation of exemplary user interface programs. It is a public effort, everyone can contribute to it by sending contributions to the Rapicorn Mailing list.
