                                     LICENSE

        This  version of the SXT Software Exploration Tools is NOT public
        domain or free software, but is being distributed as SHAREWARE.

        Non-registered users of  this  software  are  granted  a  limited
        license  for  a 30-day evaluation period starting from the day of
        the first use to make an evaluation copy for trial  use  for  the
        express  purpose of determining whether this software is suitable
        for their needs.  At the end of  this  trial  period  you  should
        either register your copy or discontinue using this software. The
        use  of  unregistered  copies  of  this software,  outside of the
        initial 30-day  trial,  by  any  person,  business,  corporation,
        government agency or any other entity is strictly prohibited.

        This means that if you use this software, then you should pay for
        your  copy.   This  software  is  NOT  free,  but  you  have  the
        opportunity to try it before you buy it.  Either pay for  it,  or
        quit  using  it.  A registration entitles you to use your copy of
        this software on any and all computers available to you. If other
        people  have  access  to  this  software  or  may  use  it,  then
        additional copies or a site license should be purchased.

        All  users  are  granted  a limited license to copy this software
        only for the trial  use  of  others  and  subject  to  the  above
        limitations.  This license does NOT include distribution, selling
        or copying of this software package in connection with any  other
        product  or  service  or  for  distribution  in any incomplete or
        modified form. Operators of electronic bulletin board systems and
        software servers (like INTERNET FTP-Servers)  are  encouraged  to
        post this software for downloading by their users, as long as the
        above conditions are met.

        This  package  is  expected  to  be  distributed by shareware and
        freeware channels,  but the fees paid  for  "distribution"  costs
        (e.g.   disk,   CD-ROM)   are   strictly  exchanged  between  the
        distributor and the recipient, and the author makes no express or
        implied  warranties  about  the  quality  or  integrity  of  such
        indirectly acquired copies. Distributors and users may obtain the
        package  directly  from  the  author  by  following  the ordering
        procedures in the REGISTER files.


                              REGISTRATION REMINDER

        Unregistered copies of this software are 100% fully functional. I
        make them this way so that you can have a real look at them,  and
        then decide whether they fit your needs or not. This work depends
        on your honesty.  If you use it, I expect you to pay for it. When
        you pay for the shareware you like,  you  are  voting  with  your
        pocketbook,  and  will encourage me and others to develop more of
        these kinds of products.


                 THANK YOU FOR SUPPORTING THE SHAREWARE CONCEPT
