Hi, I am trying to follow this tutorial to set up a xampp server for GCM: https://developer.android.com/google/gcm/ccs.html and they already give some demo python code, but the 'import xmpp' statement does not work by default. When I try to install 'xmpp' using pip from the console, this does not seem to be working either. Does anybody know how I can install xampp? The framework I am using is flask if that makes a difference. Thanks, -Alper
