GNUstep CoreBase Library Manual

The GNUstep CoreBase Library is a free software, cross-platform general-purpose utility library implementing the API of Apple's Core Foundation framework. It works on many UNIX-like platforms such as GNU/Linux, FreeBSD, OpenBSD, NetBSD and Windows, and is frequently tested on x86, AMD64 and ARM CPU architectures.

GNUstep CoreBase provides abstractions to common data types such as strings, raw data, numbers, arrays and dictionaries, supports internationalization by providing native support for Unicode strings and locale-based formatting, and includes a suite of utilities for property lists, run loops, sockets and much more.

The library is part of the GNU Project and licensed under the GNU General Public License version 2.1 or a later version.
