+First run a pvAccess test server (portable channel access server equvivalent) by
+running ./runTestServer in another terminal (or in background).
+
+pvget, pvput and eget utilities are delivered by pvAccessCPP (caget and caput equvivalents).
+They are located in pvAccessCPP/bin/$EPICS_HOST_ARCH directory.

+1. Get the value of a V4 scalar PV
+----------------------------------
+> pvget testValue
+testValue                      0

+
+2. Put the value of a V4 scalar PV
+----------------------------------
+> pvput testValue 1.23
+Old : testValue                      0
+New : testValue                      1.23
