Following a problem on fop-user I'd like to propose the removal of ant.jar and the build.bar/sh pair. I've heard that best practice is not to bundle Ant with a project, though I can't point you to a web page.
It's reasonable to expect that everybody who wants to compile a Java program to install Ant because it's so widely used. I know it's convenient that you can download FOP and simply call build.bat but removing our own ant.jar makes the distribution smaller, removes potential error sources (such as the one uncovered on fop-user and provided we have a version check in our build.xml). If nobody objects I will try to find time during the weekend to do that. Jeremias Maerki
