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 informa-
     tion 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  generated.
	    Special  values "all"/"none" have obvious meaning.	To block entries
	    from a list, add a "-" prefix.  You may use an  asterisk  "*"  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  XdbDebug()
	    etc.  will	also print their widget ID.  If the variable doesn't ex-
	    ist, then they only print their name for identification.

     DEBUG_REDIRECT_XMWARNING
	    If this variable exists any output of  _XmWarning()  and  equivalent
	    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  sys-
	    tem  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  sys-
	    tem.  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 LESS-
     TIF_PRODUCTION the relevant code sections are en-/disabled during the build
     process.
