Open source authoring tools: Introducing eXeLearning

Sorry, WYSIWYG is an acronym for "What You See Is What You Get". A WYSIWYG editor is a system in which content (text and graphics) onscreen during editing appears in a form closely corresponding to its appearance when printed or displayed as a finished product, which might be a printed document, web page, or slide presentation.

eXelearning software mimics wysiwig functionality enabling users to see what the content will look like when published
