I learned that Indus is a framework for program slicing, and kaveri is its plug-in on eclipse.The download link of Indus is http://forge.cis.ksu.edu/frs/?Group_id=12, but I can't open it.
However I found a CVS repo in github ( https://github.com/rvprasad/Indus_archive ). I put the Indus and kaveri plugin jars into eclipse's dropins, but it doesn't work. I switched to the plugins directory, it still doesn't work.
