+               For systems with really minimal memory requirements, this
+               will disable the support for WISPr hotspot logins. The code
+               for WISPr will be still compiled into the daemon, but its
+               requirement on GnuTLS for secure connections will be lifted.
+
+               The missing GnuTLS support shrinks the memory requirements
+               by about 30% and for systems that are more stationary and do
+               not log into hotspots this might be a better trade off.
+
+               Disabling WISPr support is not disabling the portal detection
+               support. A portal will still be detected, but instead of being
+               asked for login credentials, the request for a browser session
+               will be made through the agent.
