To build Showcase, you must have Ant (http://ant.apache.org) installed. 
Also, it uses a set of tasks authored by me (Andariel Ant Tasks, 
http://andariel.uworks.net), that must be installed, too.

Ant can be called on the following ways:
- "ant installxpi": Build and launch the extension. The last part will only work in Windows.
- "ant createxpi": Create the default Firefox Showcase version.
- "ant createseaxpi": Create SeaMonkey Showcase version.
- "ant createlitexpi": Create Portable Firefox Showcase version.
