    Revision history:

	0.00  1999			Petr Vandrovec <vandrove@vc.cvut.cz>
		Initial revision.

	1.00  1999, November 20		Petr Vandrovec <vandrove@vc.cvut.cz>
		Added license.

	1.01  2000, April 26		Petr Vandrovec <vandrove@vc.cvut.cz>
		Added NWDSGetCountByClassAndName demo.

	1.02  2000, April 30		Petr Vandrovec <vandrove@vc.cvut.cz>
		Added NWDSExtSyncList demo.

	1.03  2001, February 17		Patrick Pollet <patrick.pollet@insa-lyon.fr>
             Duplicated in /contrib/tcl-utils from /contrib/testing/nwdslist.c
             and renamed ncplist.c
                Added flag quiet to reduce output lines to a minimum
                Added flag abbreviate to trim out context part ( -c required)
                This program is meant to be called by a TCL/tk from end in -Q mode
                          so it should emit  the word "failed" in case of trouble
                          somewhere in the line.
                Added option -T tree
                Changed parameters -O -> -o and -C -> -c for consitency with other ncp utilities.
                TCL/tk usage to get list of contexts :
                if {$context !=""}{
                        catch  {exec  ncplist -T $tree -v 4 -Q -A -o $context -c $context -l "Org*"} result
                }else{
                        catch  {exec  ncplist -T $tree -v 4 -Q -l "Org*"} result
               }

               to get list of volumes (NDS format) ncplist -T tree -v 4 -Q -A -o ctx -c ctx -l "Vol*"

	1.04  2001, March 10		Patrick Pollet <patrick.pollet@insa-lyon.fr>
               Corrected #196 : check size of parameter -T
               Corrected #252 : removed wrong comments
               Modified  #237 : tretament of tree moved later  (if (!server))
	       
	1.05  2001, December 16		Petr Vandrovec <vandrove@vc.cvut.cz>
		const <-> non const pointers cleanup
