Cobra is open source under the MIT license which is friendly to both commercial and non-commercial projects. You will find a License.text in the source distribution (and a "read me", of course).

If you just want to install and use Cobra, see Downloads for packages.

The source code repository is now open. You can get the very latest code using Subversion like so:

svn co http://cobra-language.com/svn/cobra/trunk/ cobra-workspace

To update your workspace, simply use:

cd cobra-workspace
svn up

If you have any problems at all, please post to the Discussion Forum and we'll help you out.

If you still want the tarball of source code from the initial open source release, you can download it. But it's already out of date and there is no convenient way to update it. CobraSource-2008-02-29-03-01.tar.gz
