Thanks for those pointers Rahul. I'll be sure to add, at least the first 
one to the guide.

I had a look at the Apache Maven 1 repo at

There doesn't seem to be any consistency when looking at different 
components. I had a look at a few:

- older jars have md5
- newer jars have md5 and asc
- older poms have no md5 or asc
- newer poms have md5

- jars have md5
- poms have md5

- older jars have md5
- newer jars have md5 and asc
- older poms have md5
- newer poms have md5 and asc

How do we handle this? If the previous pom is signed then the relocated 
one should also be signed, is one way to go.

And a more philosophical question: is a pom an artifact?

Henk's page does not seem to look at the Maven repos at all, only in /dist/
