Of all the technical writing tools I’ve used over the years, Epic Editor was probably the most impressive, especially when it came to doing tech documents that involved DocBook and Dita. It was difficult to learn – no point pretending otherwise – but once I got the hang of it, I used it non-stop for over 2 years. Then I switched companies are haven’t had the opportunity to use it again. With that in mind, here is a brief intro to EPIC Editor, Ivan’s favorite XML Authoring Software!
Update: Epic Editor is now called Arbortext Editor. You can learn more over here: http://www.ptc.com/products/arbortext-editor
