WebBoy will be the second product written using the Micro PM Gui Library from the IBM Embedded Middleware Technical Office. The Micro PM is a very small GUI, for use in low memory (thin client type) software. What they have done is taken 200 or so important API's from OS/2 Presentation Manager (PM, hence Micro PM), Graphic Programming Interface (GPI), and Control Programming Interface (CPI), to make cross-porting between Micro PM and OS/2 much easier. This means that you can develop applications for the Micro PM on OS/2 and port it directly. Development is not difficult at all on a DOS only or Windows based machine.
The Micro PM is designed as a portable GUI platform, so expect to see it on other platforms soon(ish). The Micro PM for DOS has been used as a part the supporting software (PIM) for the IBM Palm Top PC110 (PersonaWare), being sold in Japan.
