Preprocessor for building GObjects GObject Builder (GOB) is a simple preprocessor for easily creating GObjects (glib objects). It reads a class description file with inline C code and produces .c and .h object files for you. It allows you to easily use most of the features of the GObject system and avoids typos by reducing the amount of code needed. In general, the amount of code is about the same as for OO languages such as Java or C++, but you still have to only use C and you get all the power of the GObject system.
