This document is intended to become a complete reference manual for GPE application development. At the point of starting this we have various sources of information about the wisdom how to create or continue a GPE application. In the past years we have been collecting lots of experience in coding for handhelds devices - it is very important not only to share the software but the experience that lead to this software as well.
