+      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.
