    longDescription = ''
      PicoC is a very small C interpreter for scripting. It was originally
      written as a script language for a UAV's on-board flight system. It's
      also very suitable for other robotic, embedded and non-embedded
      applications. The core C source code is around 3500 lines of code. It's
      not intended to be a complete implementation of ISO C but it has all the
      essentials. When compiled it only takes a few k of code space and is also
      very sparing of data space. This means it can work well in small embedded
      devices.
