+/*
+This is a short sample to show how to connect to a remote
+queue manager in a Go program without requiring external
+client configuration such as a CCDT. Only the basic
+parameters are needed here - channel name and connection information -
+along with the queue manager name.
+
+For example, run as
+   clientconn QMGR1 "SYSTEM.DEF.SVRCONN" "myhost.example.com(1414)"
+
+If the MQSAMP_USER_ID environment variable is set, then a userid/password
+flow is also made to authenticate to the queue manager.
+
+There is no attempt in this sample to configure advanced security features
+such TLS.
+
+If an error occurs, the error is reported.
