+ *                   dbgtext( "Some text.\n" );

+ *               (i.e., no '\n').  See debug.c:dbghdr() for more info.
+ *               Example usage:
+ *                 DEBUG( 2, ("Some text.\n") );
+ *  DEBUGADD() - If level <= DEBUGLEVEL, then the text is appended to the
+ *               current message (i.e., no header).
+ *               Usage:
