D is a general purpose systems and applications programming language.

The D programming language is a higher level language than C++, but retains the ability to write high performance code and interface directly with the operating system API's and with hardware. D is not a scripting language, nor an interpreted language.

The Digital Mars D Compiler (DMD), is also available for various systems

DMD by Digital Mars, see http://www.digitalmars.com/d/1.0/

The official D "reference" compiler, DMD, is based on the same back-end as the Digital Mars C/C++ compiler for Windows. The GDC compiler was made by adapting the DMD frontend source code, to work with the regular GCC backend.

The GCC D Compiler (GDC) is based on the GNU Compiler Collection (GCC)

GDC by David Friedman, see http://dgcc.sourceforge.net/

You can run programs created with GDC on any Mac OS X machine (no special run-time libraries required) It is also possible to link with programs created by the Apple versions of the GCC C Compiler (gcc) and the GCC C++ Compiler (g++).
