* Example usage:
* if( DEBUGLVL( 2 ) )
* dbgtext( "Some text.\n" );
* DEBUG() - 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") );
