Contacts:

   Pierre Jelenc, [e-mail], will maintain and
   distribute documentation and support files for translated versions of
   TDE.  Some users are interested in using TDE with non-English
   languages.  Check with Pierre before you translate the documentation,
   as he may have the language version you need.  Incidentally, Pierre
   is also developing a language independent sort program.

   For those in the Department of Defence, Tom Waters,
   [e-mail], will be available to answer questions
   and provide support.  He has worked with TDE source code since
   version 1.0, so he knows how the guts of the program works.  Usually,
   the hardware and software at DoD are from the same manufacturor, so
   he may have a version of TDE that takes advantage of the capabilities
   of those machines.

Claimer:

  I use this program all-day-every-day on all of my FORTRAN, C, and
assembly source code at home and at work, Frank Davis.


Licensing:

  This program is released into the public domain.  You may use and
distribute it freely.  There is no copyright, no fee for use, no
licensing, or no registration.  This editor is not user supported,
corporate sponsored, or government subsidized - it is sustained and
maintained solely by Frank Davis.  This editor was written for use not
only as a simple text editor but also as a learning tool.  Examine the
code and discover the basics of editor construction.  Experiment a
little and add your favorite functions or modify the existing functions
to suit your needs/requirements/tastes/etc.  If anyone includes TDE with
their own software, please use common courtesy and give Doug Thomson and
Frank Davis credit for their work (that's the only payment I ask).  If
you release any changes or additions to the TDE editor, please observe
the original spirit of Doug Thomson's DTE 5.1 and release the changes as
public domain software.



Legal Legal Stuff:

  Six years ago, as an employee of the Federal government, as part of
my official duties, I wrote several editors that use a double linked
list.  The new scheme in TDE 2.2 uses a double linked list.  Some of the
concepts and/or code and/or techniques that I used to develop those
editors as part of my official duties are incorporated into TDE 2.2.
Being that my current official duties as an employee of the Federal
government requires that I maintain and support those editors, as a
matter of law and ethics, version 3.1 of TDE is released into the public
domain.  It's not so much that I want to release TDE into the public
domain, but more so, it's the law that requires that I release TDE into
the public domain.  Not only is TDE 3.1 based on DTE 5.1, the public
domain editor by Doug Thomson, but it is also based on works of the
United States government, written and currently maintained by my
ownself, Frank.  Many of the ideas that are incorporated into TDE were
derived from editing tasks needed on the job.  Copyrighting off-the-job
what I do on-the-job would not be ethical.

       "Definitions"

          'A "derivative work" is a work based upon one or more preexisting
           works, such as a translation, musical arrangement, dramatization,
           fictionalization, motion picture version, sound recording, art
           reproduction, abridgement, condesation, or any other form in
           which a work may be recast, transformed, or adapted.  A work
           consisting of editorial revisions, annotations, elaborations,
           or other modifications which, as a whole, represent an original
           work of authorship, is a "derivative work".'

          'A "work of the United States Government" is a work prepared
           by an officer or employee of the United States Government
           as part of that person's official duties.'


     Section 105, page 1310:

           any work of the United States Government, but the United States
           Government is not precluded from receiving and holding copyrights
           transferred to it by assignment, bequest, or otherwise.'

             particular circumstances create an appearance that the
             law or these standards have been violated shall be
             determined from the perspective of a reasonable person
             with knowledge of the relevant facts.'


Distribution Sites:

  You will always be able to find the latest version of TDE in the
SIMTEL20 archives in the PD1:<MSDOS.EDITOR> directory, in Library 16 of
Utilforum/Tips forum in PC MagNet on CompuServe (search for TDE as the
keyword), or on the Keystone Connection BBS, Keystone Heights, Florida,
USA, in directory 9, DOS help/utils.  I do not upload TDE to any other
file archive, Frank.
