First off I wanna say that I'm running all my Ant task via Eclipse and not the command line. If there is a demand to know how to install Ant and run it from the command line I'll do that post separately.
So, what is Ant? Well to steal a quote from Mark Drew, think of Ant as .bat files on steroids. You use XML to describe a set of commands to run a whole range of tasks to do anything from SVN/CVS checkouts, unit tests, FTP, emails, sql, moving/copying folders/files generally just name it!
In this guide I want to cover creating a build.xml file and moving files/folders. I'm assuming you've got Eclipse and you know you way around it enough. Before we do begin you will need to ensure that you can see the Console View.
