Preliminaries

The environment we have in mind is one controlled by two main tools, both of which require some configuration:

• your Java IDE for authoring code and configuration, as well as for versioning code (Eclipse from now on);
• your shell for building and deploying code, as well as for all the other administrative tasks (bash from now on).

Starting with Eclipse, open a fresh Workspace and make sure it is associated with a suitable version of the Java 5 compiler.
