+GLib is a general-purpose, portable utility library that provides many useful 
+data types, macros, type conversions, string utilities, file utilities, a 
+mainloop abstraction and more. It is a low-level core library that forms the 
+basis for projects such as GTK+ and GNOME. GLib provides data structure 
+handling for C, portability wrappers, and interfaces for such runtime 
+functionality as an event loop, threads, dynamic loading, and an object system.
