Adding Distributions via config-distro.rb

In looking at the Admin manual, there is a high level example of using config-distro.rb to add new distro's, however no examples or pointers to any of the distro URL's.

We're interested in deploying Cloudera CH4 as a test, but don't have the full ruby script URL input's for the distributions.  I believe I have the primary distro, but unsure on PIG and hive.

So far, I have this:

cd sbin

config-distro.rb --name Cloudera 4 --hadoop http://archive.cloudera.com/cdh4/redhat/6/x86_64/cdh/4/

Any info or examples for adding a full CH4 distro?
