Somusar's Francesco Aliverti-Piuri takes up the challenge of producing an application in a weekend, armed only with some sample content from myself and his Software Production Machine (SoProMach) system. His account of the weekend, and notes on how he created the other sample application here, Barcelona, should give you a good idea of the scope of SoProMach.
Parts of Francesco's article read a little like we're giving him free advertising, but any system that allows people to get their ideas onto Symbian OS without having to learn C++ is a good thing as far as we're concerned. I have to say, as someone used to OPL and Python, SoProMach doesn't seem that much easier to get to grips with, but each RAD system has its strengths and weaknesses. In this case, there's a learning curve to climb, but once climbed, applications should be quite quick to 'produce'. You should also note that the system also requires you to have installed the official C++ SDK as well, as a background tool.
