[Mentors] Advice on branding of Apache NetBeans book

[Walter Nyland]

Hi mentors,
We're updating https://leanpub.com/nbp4beginners.
We want to:
-- use the name "Apache NetBeans" and "Apache NetBeans Platform" instead of 
"NetBeans" and "NetBeans Platform"
- use the Apache NetBeans logo
Is this allowed? Must any text be added to the book to allow this? Any 
licensing involved?
Thanks,
Walt
