title: How to compress every file in a folder using Ant and Gzip
body: <p>Suppose I have a folder with many files. I want to have a .gz version of each file (not a tar.gz with all files). How do I do that with Ant? Ant's  doesn't accept a list of files, only operates on one. So how do I repeat this for all files, with a certain extension, in a directory?</p>
