another unexplained speed bump getting this configuration to work. When you run/debug
the extensions from eclipse debug-as menu item, files are copied from the project to windows
c:\users\<username>AppData\Roaming\Adobe\CEP\extensions
however, the manifest file is copied from a second, hidden copy in <project>.staged-extension\csxs
instead of the official csxs\manifest.xml.
editing the visible copy of the manifest file has no effect.
