 NAME
      LessTif - an open-source Motif replacement



 SUMMARY
      LessTif is a free replacement for OSF/Motifr.

      As with Motifr, 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
           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
           exist, 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 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.
