echo
echo Services are online!  The following shell offers a 'wire_transfer'
echo command that wires money to Nexus 'test-user'.  Give it after having
echo connected an HTTP client that long-polls to Nexus.  As an example, a
echo 100 seconds long-poller to Nexus is the following command:
echo curl -v -u test-user:x "'http://localhost:5001/facades/test-facade/taler-wire-gateway/history/incoming?delta=5&long_poll_ms=100000'"
echo
echo Hint: after having issued the previous command and having observed
echo that it actually long-polls, press CTRL-Z to send it in the background,
echo "then wire the funds to the long-poller with 'wire_transfer',"
echo "and finally give 'fg 1' to bring the long-poller in the foreground."
echo If the client now shows a response, then the long-polling mechanism
echo worked.
