# Test whether shared subscriptions work

# Client 1 subscribes to 02/#, non shared. Should receive everything.
# Client 2 subscribes to $share/one/02/share/test
# Client 3 subscribes to $share/one/02/share/test and $share/two/02/share/test
# Client 4 subscribes to $share/two/02/share/test
# Client 5 subscribes to $share/one/02/share/test

# A publish to "02/share/test" should always go to client 1.
# The first publish should also go to client 2 (share one) and client 3 (share two)
# The second publish should also go to client 3 (share one) and client 4 (share two)
# The third publish should also go to client 3 (share two) and client 5 (share one)
