Hmm, thanks, Robert.

The Sun docs' example makes a better case for their way of doing it than the 
Apache example does.  In particular "Implementation-Version" boils down to 
basically a build number which is not clearly shown in the Apache example.  
Of course we don't use these in Commons-net and it would be hard in an open 
source project where we lack a "build machine", but at least you see the 
point of having the key there.

You've caught me out.  I really did try to do it the Apache way but I couldn't 
figure out how to make Maven give me an Implementation-Title.

I created a manifest file, and put the Implementation-Title key-value pair 
there, then I defined the property maven.jar.manifest in 
to point at the location of this file.  Maven docs indicated that this would 
cause Maven to merge the default manifest with this one, but when I was done, 
the manifest created was no different.  It was then that I noticed the 
package key containing the same data and got lazy and decided that that was 
good enough.

But if you or someone else can point me at the correct way of making Maven do 
the right thing, I'll be happy to follow.
