<C></U>Preamble:<!U>
From Glover's original text:
   The Cdk curses widget set was written by myself (Mike Glover). It started
as a small pet project to test how compatible my new Linux box was to other
flavours of Unix. As it turned out I discovered Ncurses, and played with 
that a whole lot. This constant playing with Ncurses created what is 
currently known as Cdk. Cdk has evolved many times since its first inception
and has evolved to what you are currently looking at. One day I finally told 
myself that the C version was 'done'. I quickly looked in other directions 
for the Cdk widget set. One day I told myself:

<C>"Cdk would be really cool if it was
<C> interpreted instead of compiled! "

Enter Mike's love of Perl. It finally dawned on me that I could extend Perl5
to include the Cdk widget set. So I started to play with Perl5. The more I 
played with Perl5, the more I really started to like the additions. I 
finally read the manual pages on how to extend Perl5 to include other 
libraries. As time passed I entrenched myself deeper into extending Perl5 to
what I currently call the Cdk Perl5 extension. After about 2 months of work,
Cdk was finally extended into Perl5.  (crowd cheers...)

</R>Info:<!R>
   I'm sure the first question being asked is, 'What does Cdk
stand for?'. In response I say : (fanfare please)

There are currently 22 widgets available in Cdk, with more coming. What they 
are and what they do is in the following table.

Each help subsection outlines certain features of each widget. They are 
broken up into the following sections:

<B=*>Purpose
<B=*>Construction Options
<B=*>Available Methods
<B=*>Key bindings
<B=*>Tips & Tricks
<B=*>Physical Restrictions
<B=*>Example Use Of The Widget

The documentation supplied with the demo is more than enough information
to get any user off the ground and flying with the Cdk Perl5 extension.

Have fun.

Just in case, there is a subdirectory named examples which provides 
individual examples of each Cdk widget.

ttfn,
     Mike
