How many times has this happened to you? You've written a little
Java utility, or maybe even a more complex application, and you
want to create Mac OS X application bundle for easy distribution.

You'd like to be able to do it automatically from your build
process, but you're forced to go run the Apple Jar Bundler and
tweak all the settings manually every time you build.

Well no more! JarBundler is a feature-rich Ant task which will
create a Mac OS X application bundle from a list of Jar files and
a main class name. You can add an Icon resource, set various Mac
OS X native look-and-feel bells and whistles, and maintain your
application bundles as part of your normal build and release
cycle. It is free software licensed under the GNU General Public
