+ * Class to provide app access to files outside of the currently logged in user's data
+ * folder. Functions are provided to create a "view" into ownCloud's virtual file  
+ * system, and an API similar to the oc_filesystem class is available for manipulating
+ * those files (including the ability to read, write, and delete files).
+ * 
+ * Every view can have it's own chroot, giving it access to a part of the 
+ * filesystem and will provide the same functionality as oc_filesystem.
+
+ * For instance an app can create a new filesystem view on a data folder belonging
+ * to a user other than the one logged in, so that it may change the files there 
+ * (use case: enabling sharing of files).
