Workbone - With Volume Control - How To Install?

["Scarletdown" <gsutton9503@charter.net>]

i just tried out the workbone CD player that is installable via apt-get.  It's a decent console-
based player, except for one problem.  It has no volume control.

Anyway, I did a bit of snooping around and came across this:

http://www.eleves.ens.fr/home/derouler/info/workbone/index.html.en

That is the same player, but with the + and - keys set to provide volume control.

I downloaded it and uncompressed it, but now, how do I actually install it?

The files that are now sitting in my home directory after uncompressing the tgz file are:

hardware.c
workbone
workbone.h
struct.h
workbone.c

So, what does I have to do with these to get a working player?  The site the tgz file was 
downloaded from has no instructions on how to install this.
