+# Template of main python server wrapper
+# Solves the problem of pogo generated Tango server file names  which are not easily handled by databeds and Starter.
+# 1) copy this template in the server directoy using the canonical server (executable) name: cp ../python-srv.template myclass-srv
+# 2) chmod +x myclass-srv
+# 3) edit myclass-srv ename MyClass to the actual class name of the python Tango server (you can also clean up these notes)
