Javadoc newbie - how to get "USE" content

Question

I don't understand how to get content from the USE button. At the moment all my attempts produce a USE button which links to a page stating something like "No usage of root.package.class".
My current argument string for Javadoc is something like
-d c:\Doc -use C:\Source\
This doesn't work (produces a nice set of pages with the above problem on the "USE" page). To be specific there is no USE content even for two classes in the same package where one is used by the other.
I've tried guessing some longer combinations of terms leading up to:
-d c:\Doc -use -sourcepath C:\Source\ -classpath C:\Classes\ -subpackages root.packageA root.packageB C:\Source\*.java
though still to no avail. Please can someone offer some advice? Thanks very much

No. Imports are considered by Javadoc to be part of the implementation. If you notice, javadoc does not document imports. Imports are completely ignored by Javadoc, other than to resolve names.
A "use" is where a type appears in a declaration, not an import or other implementation.
"Given class C, things that use class C would include subclasses of C, fields declared as C, methods that return C, and methods and constructors with parameters of type C."
http://java.sun.com/j2se/1.5.0/docs/tooldocs/windows/javadoc.html#use
Example 1: Class A does not use class B:
import B;
public class A {
     new B();
public class B {
Example 2: method getValue uses B:
public class A
    void getValue(B b) {
public class B {
}
