CBE (Pt1.), Unix Pipelines, Subtractor, Multiplexer			[TOC]
===================================================

This session has the following topics:

- A __Unix workout__ for using useful commands together with so called Unix
  pipelines,
- In the first part of the _C by Example_ series you get some __technical
  background__ that is required to understand the programming language in
  general.
- You will build a __4-bit subtractor__ on top of your previously build 4-bit
  adder.
- For a nice chill out we use a __multiplexer__ to combine the 4-bit adder and
  4-bit subtracter into a multi-use tool and provide a nice demo.
