Hi Torsten, You might be interested in the TutorialBrowser in http://ss3.gemstone.com/ss/SpaTutorial It uses Glamour to build both tutorial texts and exercises where the exercise can be done directly in the browser. To see all, you need to load the data from the attached zip. Set the loading director in the Configuration (bad name, I know) The latest version is the XpDays2012 Next step would be to integrate the markdown parser and create better looking texts.
