 *               function name.
 *               Returns True if the debug level was <= DEBUGLEVEL.
 *               Example usage:
 *                 if( DEBUGLVL( 2 ) )
 *                   dbgtext( "Some text.\n" );
 *  DEGUG()    - Good old DEBUG().  Each call to DEBUG() will generate a new
 *               header *unless* the previous debug output was unterminated
 *               (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:
 *                 DEBUGADD( 2, ("Some additional text.\n") );
