Has anyone written a tool like this?

Path Tool

This suggested student project is a tool that helps you deal with
duplicates on the path and classpath. It also helps you find files
that should be on the path or classpath but are not.

It displays the path and classpath with one element per line. It lists
the jar names in the currently active ext directory, and the name of
that directory.

I tell it someprog.exe then it tells me all the places on the path it
found someprog.exe

I tell it someprog and it tells me all the places on the path it found
someprog.exe, someprog.com, someprog.bat, and someprog.btm then tells
me which one I would get.

I tell it com.mindprod.bulk.SomeClass.class It tells me all the places
on the classpath (including the active ext jars) that it finds this
class, and tells me which one java would actually use. The package
name is optional.

I tell it com.mindprod.bulk.SomeClass.java It tells me all the places
on the classpath (including src.zip) that it finds this class, and
tells me which one javac would actually use. The package name is
optional.

I ask it to search my entire hard disk and the contents of all jars
and report as above.
