Need help for my first ivy file

[an...@free.fr]

Hi all,
I'm trying to use ivy to resolve ant4hg project dependencies... but I don't
understand everything !

For compiling ant4hg, I need :
- ant.jar
- ant-launcher.jar
- commons-cli.jar

For unit testing ant4hg, I also need :
- ant-unit.jar (not found on the maven repository :
http://repo2.maven.org/maven2)

For using ant4hg as an ant tool, we just need :
- ant4hg.jar (to put in ant lib directory)

For using ant4hg as a standalone command line tool, we need :
- ant4hg.jar
- ant.jar
- ant-launcher.jar
- commons-cli.jar

Here is my ivy.xml file.
I don't really know how to configure dependencies :
[<dependency...conf="standalone->default".../>].
What do you think about it ?
