LyX version 2.0.7 has been ported (4/17/2014) to OS/2. LyX is an open source WYSIWYM (what you see is what you mean) GUI document processor. Unlike standard word processors, LyX encourages an approach to writing based on the structure of your documents, not their appearance. LyX lets you concentrate on writing, leaving details of visual layout to the software.
