This is the pick message conversion module from NEIC. It reads TYPE_PICK_SCNL from its input ring and writes TYPE_PICK_GLOBAL to its output ring. The same information is contained in both message types but the format is slightly different. One example of using this module is providing regional/local picks from pick_ew as input to glass, the global associator. The conversion will be performed for any TYPE_PICK_SCNL message found on the input ring.
