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
              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.
