title: Concatenating JavaScript files using Ant
body: <p>I have about 50-60 js files and there are dependencies among them so I need to maintain an order while cocatenating. Writing all the names in "files" attribute would make the build.xml messy and any addition of js files in future would need to added accordingly. So, I wanted to write the order in a separate txt file and just copy the contents using Ant following that order. Is it possible ?  </p>
