Dart documentation is available as follows.

For additional information, refer to the Dart mailing list, or study an existing implementation (such as ITK or VTK). You can obtain access to this code as follows.

To obtain access to the ITK CVS repository:

Insight (ITK) is the first project to adopt Dart. It is heavily templated C++ code using the generic programming style.

cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight login
(respond with password insight)

Follow this command by checking out the source code:
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co Insight

To obtain access to the VTK CVS repository:

This repository will soon be an "experimental" Dart-based environment. VTK 4.0 will use Dart in preference to the current testing environment. VTK is a very large system for 3D graphics and visualization consisting of approximately 700 classes and hundreds of thousands of lines of executable code. It fully exploits Dart's capabilities by performing nightly builds and tests on a variety of platforms.

cvs -d :pserver:anonymous@www.vtk.org:/cvsroot/VTK login
