+Modifications copyright Thomas Dickey 1999-2015,2016
+
+The software and documentation are still under the same licensing are the
+original Cdk, but noting that substantial work and enhancements have been made,
+I've added my name as needed -TD
+
+The original COPYING file follows (with corrections as noted in CHANGES).

+Cdk Copying Guide
+Copyright Mike Glover, 1995, 1996, 1997, 1998, 1999
+-------------------------------------------------------------------------------
+In order to copy Cdk around I have some requirements that will protect me,
+and possibly even you. First thing, I feel I should say that this little project
+of mine has taken quite a bit 'free' time and I have put a lot of work 
+into it. I do ask that if anyone asks you about Cdk, tell them where you got it
+and who wrote it. If you see Cdk installed without this file on the system
+somewhere, then assume the copy the person has is a 'corrupt' version. I will
+not be responsible for any unfortunate results if someone else makes a personal
+modification to the Cdk library. I will also not be responsible if for some
+reason the installation of Cdk creates a negative effect on your machine. You
+do have my word that there are no "Trojan horses", worms, or other security 
+worries lurking in this code. If there are I did not put them there and you
+should remove the version of Cdk you have and go get a proper copy. I hate 
+virus writers as much as anyone else!
+
+Instead of writing my own license (I'm a programmer, not a lawyer!) I'm going
+to adapt the BSD public license on public software. If you do not agree to
+this license then remove the Cdk distribution and we all will be happier in
+the end. Here is the complete BSD public license in its true form, for
+reference.
+
+I will say one thing, Cdk is my copyright.  I will continue to support any
+released versions out there as long as they are in their released form.  I am
+releasing this into the "public" because I feel I have benefited from other
+people's hard work, I'd like to chip into the pot as well.  This does NOT make
+Cdk public domain though.  Cdk is still my copyright, and owned by me, I am
+merely stating this so I don't see 40 different versions of my code floating
+around with other people's names attached.
+
+With that ugly stuff said, I will happily take any comments or questions about
+Cdk.  Input is more than welcomed.  In fact I encourage it.  Feel free to mail
+me and ask questions you think the supplied documents don't cover.  If I get
+enough I may build a FAQ to help newcomers.  (We'll see how Cdk is accepted
+though).
+
+For you Perl programmers, there is a Perl5 extension to Cdk. Look at your
+closest CPAN site under authors/id/GLOVER.
+
+If you want to get a hold of me mail me at one of the following:
