CALDES is a sub-system of Coimbra which allows to compile interactive slide shows and short animations. For developing an application based on CALDES, you collect resources (text, audio and visual material) and compile this material into several resource files. The resource files are then interlinked to produce an interactive application.
For each frame of the slide show you can define buttons, pointers, text to be displayed and sound to be played. A maximum of three actions may be assigned to each button in order to control the flow of the CALDES application.
