If you don't have the sync indicator and service already running in Unity,
you can build and run the demo app this way:

 $ cd src
 $ make
 $ export G_MESSAGES_DEBUG=all
 $ export INDICATOR_SERVICE_REPLACE_MODE=1
 $ export INDICATOR_ALLOW_NO_WATCHERS=1
 $ service/indicator-sync-service &
 $ indicator-loader3  indicator/.libs/libsyncindicator.so &
 $ cd ../examples/
 $ make sync-app-example
 $ ./sync-app-example
