The Gnustep Base Library is a library of general-purpose, non-graphical
Objective C objects.  For example, it includes classes for strings,
collections, byte streams, typed coders, invocations, notifications,
notification dispatchers, times, network ports, remote object messaging
support (distributed objects), event loops, and random number generators.

It provides functionality that aims to implement the non-graphical
portion of the OpenStep standard.  In many cases, the @samp{NS*} classes
are implemented as wrappers around more featureful GNU classes.
