CNET has its own internal source code, but in an effort to share these files we're using an external SVN service (Google code). You can download files individually from our svn repository here:
Additionally, you can check out the source code with svn thusly:
svn checkout http://cnetjavascript.googlecode.com/svn/trunk/ cnetjavascript
Or browse the code source directly: http://code.google.com/p/cnetjavascript/source/browse
Check out our nifty download page powered by the same interface that runs the one on Mootools.net: http://clientside.cnet.com/js (this is the MooTools 1.2 download page)
CNET's javascript library has been ported to MooTools 1.2 and is currently in beta testing. Clientside 1.2 RC2 is the current version available. You can find the old libraries for 1.11 in our SVN repository above.
