The fourcdnsmgr5 and fourcdnsmgr6 GUI utilities are based upon the
wxWidgets object library. 

We are distributing the binary for our utility, under the wxWindows license, 
which allows our distribution based upon our own terms. 

Any independent distribution of wxWidgets by users of this software must 
be governed by the wxWindows license.  See the wxWidgetsLicense.txt file 
included.
