+Contains the JavaScript Client, Tests and Examples.
+
+The JavaScript Client library is designed to run from the same server (URL) as 
+your CMIS Server. Depending on the implementation the cmisclient.js (and the additional
+html files) can be dropped into the repository and accessed with a browser.
+
+To get started just drop all the files in the webroot in your repository and access
+the index.html.
