+## Automatic test module for SIPp.
+##
+## This module will need a test driver for each SIPp scenario:
+## - For simple scenario, i.e: make/receive call (including auth), this
+##   test module can auto-generate a default test driver, i.e: make call
+##   or apply auto answer. Just name the SIPp scenario using "uas" or
+##   "uac" prefix accordingly.
+## - Custom test driver can be defined in a python script file containing
+##   a list of the PJSUA instances and another list for PJSUA expects/
+##   commands. The custom test driver file must use the same filename as
+##   the SIPp XML scenario. See samples of SIPp scenario + its driver
+##   in tests/pjsua/scripts-sipp/ folder for detail.
+##
+##   Here are defined macros that can be used in the custom driver:
+##   - $SIPP_PORT	    : SIPp binding port
+##   - $SIPP_URI	    : SIPp SIP URI
+##   - $PJSUA_PORT[N]	    : binding port of PJSUA instance #N
+##   - $PJSUA_URI[N]	    : SIP URI of PJSUA instance #N
