Changes

In this walkthrough we will be creating a simple binary XPCOM component using the build system, called '''FirstXpcom'''. While this component won't do very much yet, it will provide a starting point for many other types of components you may wish to build down the road.

The code functionality of this component will become part of a Gecko-enabled application (in this case, a Firefox binary extension). However, it is important to remember that this is only one of many possible uses for it.
