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.
