+"""A stub sipserver for testing lmwsip
+
+This is a stub sipserver that implements a small subset of the sip
+protocol to perform unit tests.
+
+Implements the following commands:
+
+  CMD> LI USER,PASS
+  ANS< !
+
+  CMD> TI LMW
+  ANS< ! 20-JAN-01 00:00:00
+
+  CMD> WN LMW,DUMMY,H10,+HH:MM,yyyy-mm-dd,HH:MM,DATA
+  ANS< ! 1/10,;2/10;....
+
+  CMD> WN LMW,DUMMY,H10,+HH:MM,yyyy-mm-dd,HH:MM,DATB
+  ANS< ! 1/10/0;2/10/0;....
+
+  CMD> WN LMW,DUMMY,H1,+HH:MM,yyyy-mm-dd,HH:MM,DATA
+  ANS< ! 1/10,;2/10;....
+
+  CMD> LO
+  ANS< !
+
+All other commands result in a "?"
+
+  CMD> *
+  ANS< ? ERROR
+
+Note:
+   for a WN command the time and date are ignored.
+   The duration is used to calculare the number of results to send.
+
+   The sip syntax for time is much flexibler.
+   The stub only support this format!
