/*
  jcmess: A simple utility so save your jack-audio mess. Fully written in c++.

          Based on Juan-Pablo Caceres JcMess , but without Qt hooks.

          Also jcmess does not save to an XML file but to a simple text file as 
                client:port -#- client:port 
          so the separator is " -#- "
