A new version of Nanodesktop SDK is on Visilab website.

Nanodesktop SDK adds three important features to the previous:

a) Support for Python language
b) Support for PSP serial port
c) A fastest Phoenix graphical system

I want to remember that Nanodesktop is a SDK for the development
of simple applications for PSPE/PSP. The system supports development
under Windows or under Linux.
