+# Read the Github profile of `username' and obtain user's
+# name and avatar_url to create a CARD JSON payload to
+# be published retained to owntracks/username/device/info

+# You probably want to do this:

+# mosquitto_pub -t owntracks/jane/phone/info -r -f card.json

+# Note: the two commands cannot be piplelined (mosquitto_pub -l)
+# because of a bug in mosquitto_pub: https://bugs.eclipse.org/bugs/show_bug.cgi?id=478917
+# If you have a newer version it should work fine.
