Hi.  I was hoping someone could clarify some small points for me.  I 
read some on-line material, but I want to make sure I'm understanding 
things correctly.
1. What is the difference between 'use' and 'require'?
2. What is the advantage to using 'require' (if there is one)?
3. What are the implications for object-oriented programming?
Thanks for your time.
