First you have:

which isn't built from source in the package (so it's removed from the
Debian package, making a +dfsg1 package), then there's lots of
"minified" javascript, like:

Because WebSocketMain.swf is removed, this makes it a bit useless to use
this project (as it will not carry the compatibility layer for the older

sockjs-client doesn't have all of these problems, and is javascript
only, which seems a lot cleaner (requiring flash... hum... do I have to
explain why that's bad? :) ).
