NAME
       LessTif - an open-source	Motif replacement

SUMMARY
       LessTif is a free replacement for OSF/Motif(R).

       As  with	 Motif(R), LessTif consists of a widget	set, a window manager,
       and a UIL implementation	(libMrm	and the	UIL  compiler).	  In  LessTif,
       our  main  area of attention is the widget set.	We also	have a working
       window manager mwm, but UIL is not under	very active development.

       LessTif is licensed under the LGPL, the	Library	 Gnu  Public  License.
       The  license  itself accompanies	LessTif	in the file COPYING.LIB.  More
       information can be obtained from	the Free Software Foundation.

DEBUGGING
       For more	info on	Debugging check	out our	documentation in HTML format.

ENVIRONMENT VARIABLES
       DEBUG_SOURCES
	      Colon-separated list of files from which debug output is	gener-
	      ated.  Special  values  "all"/"none"  have  obvious meaning.  To
	      block entries from a list, add a "-" prefix.  You	may use	an as-
	      terisk "*" as a wildcard as well.

       DEBUG_FILE
	      If this variable exists, then the	file is	being used for output.
	      If "%p" is part of the value of DEBUG_FILE, then it is  replaced
	      by the current process id.

       DEBUG_PRINT_WIDGETID
	      If  this	variable  exists, then all widgets printed with	XdbDe-
	      bug() etc. will also print their widget  ID.   If	 the  variable
	      doesn't  exist,  then they only print their name for identifica-
	      tion.

       DEBUG_REDIRECT_XMWARNING
	      If this variable exists any output of _XmWarning()  and  equiva-
	      lent functions is	sent to	the file specified by DEBUG_FILE

       DEBUG_SIGNAL
	      Specifies	 the name of the signal	which should be	used to	switch
	      the built-in LessTif debugging system.  Valid values  depend  on
	      the  system on which LessTif was compiled	and is running and are
	      a	subset of:

	      SIGUNUSED, SIGUSR1, SIGUSR2, SIGUSR3, SIGBREAK

       DEBUG_TOGGLE
	      Specifies	the initial status of the built-in  LessTif  debugging
	      system.  Valid values are	'on' and 'off'

INTERFACES
       The  following  interfaces  exist  to Set, Toggle and Query the current
       status of the debugging subsystem:

       void _LtDebugSet	(Boolean flag);

       void _LtDebugToggle (void);

       Boolean _LtDebugQueryState (void);

SOURCE CODE
       The major part of the source code which implements the debugging	system
       of LessTif resides in /lib/Xm/DebugUtil.c Using the preprocessor	define
       LESSTIF_PRODUCTION the relevant code sections are  en-/disabled	during
       the build process.
