 The chat and call UI are automatically started by telepathy-mission-control
 when receiving or requesting a chat/call. In order to use your custom version
 you have to kill any existing instance of empathy-{chat,call} and then start
 it with EMPATHY_PERSIST=1 to prevent it from auto exiting if there is no
 channel to handle. For example:
-  EMPATHY_PERSIST=1 ./src/empathy-chat
+  EMPATHY_PERSIST=1 ./tools/empathy-env ./src/empathy-chat
 
 Debugging can be turned on using EMPATHY_DEBUG=all and logged to a file
 with EMPATHY_LOGFILE=/tmp/empathy.log
