Moving Pig's code

[Alan Gates]

As part of our move to a TLP we need to move our code base out of  
svn.apache.org/repos/asf/hadoop/pig/ and into svn.apache.org/repos/asf/ 
pig/

I plan to do this move tomorrow.  It should not affect any of your  
outstanding checkouts (including ones where you have made changes), as  
there is a simple SVN command that will change your checkout to be  
based on the new repository.  Once I do this all checkouts will need  
to happen from the new repo.

I'll send another message once it's done which will include info on  
how to update your existing checkouts.

Alan.
