simple template plugin, replace the various functions with your own, and change the g15plugin_info struct below to suit,
   edit Makefile.am and compile.  Add salt and pepper to taste.  For a more advanced plugin that creates it's own lcd screens on-the-fly, 
   see the tcpserver plugin in this directory.
