The DXGL source code will be moving its primary repository to GitHub in the near future. The repository will be able to be found at the following URL:
https://github.com/dxgldotorg/dxgl
In order to access the current development repository you will need a Git client. Windows users can go to https://git-scm.com/download/win to download the Git for Windows client if it isn't already installed. The build system as of next revision will prompt to download and install this client if it cannot find a usable copy in the registry.
The DXGL GitHub repository can now be cloned from the following URL:
https://github.com/dxgldotorg/dxgl.git
The Subversion repository will be retired at this point, and will no longer serve any new revisions.
