   1 /** @file
   2  * A file of debug printing stuff for conversation-related things,
   3  * although really anything can use this so long as it includes this
   4  * header file and defines DEBUG_CONVERSATION in conversation.c
   5  *
   6  * define DEBUG_CONVERSATION before including this file to turn on printing
   7  * and also define it in conversation.c (because it has the indent variable)
