Ant - target hierarchy of build.xml file.

I have got a long build.xml that contains plenty of targets. Some of them already not in use.

Is there any tool that can be used to figure which ant targets are being called inside this file. (of course that it won't be able to figure which targets are for external use that is being called from outside but with those I'll handle).

I open the build file in eclipse (version 3.5) but there is no such assisting tool.

Does anyone know of a tool that does it?

Search for "ant +graphviz"; there are at least three tools that will use GraphViz to draw a target dependency graph.

I knew that the ranch won't fail me.
What a briliant people here.

I indeed found this: http://vizant.sourceforge.net
And this is even more than I expected.

Thanks!
