ANT is Another Neat Tool. It is a
Java (as in written in, not necessaily for) build tool for applications - the common comparison is with the UNIX MAKE command. It allows the configuration of the common tasks in a project build process in a way that anyone involved in a project can quickly and simply build and deploy the application.

strong urge to not reply to a post written in IM/AOL speak here - in future omar bili you might want to stick to English)
