This review request (add a new jdeps tool in the JDK) include changes in langtools and the jdk build. I would need reviewers from the langtools and the build-infra team.

Webrev for review:

The jdeps source is in the langtools repo. The change in the jdk repo is to add the new jdeps executable. I made change in the old and new build for the addition of this new jdeps tool. I discussed with Jon whether I should modify langtools/make/build.xml to add a new jdeps target. Since the old build will be replaced by the new build soon, I simply add com/sun/tools/jdeps as part of javap.includes.

Alan,

The -d option is kept as a hidden option and use as implementation. We can remove it when it's determined not useful in the future. I also rename -v:summary to -summary.

Thanks Mandy
