If you decide to publish your lecture material with eSkript you might have periodical changes of your content. With the web version of your eSkript you can always provide the latest and most updated version. However, the static files (PDF, EPUB, MOBI) need to be recreated every time you want to include an update. In order to keep track of the different versions, it makes sense to include for example the date of the last update in the export files. Like that the reader always knows whether he/she is working with the up-to-date version. Below you find a possible solution on how to include the export date.
