Obtaining the Liquibase source code

I wanted to take a quick look at liquibase.servlet.LiquibaseServletListener so that we can extend it for our own customer listener as part of our integration with Liquibase but I cannot for the life of me find the source code.

Am I missing something? I could not find links to the source on the download page. Any pointers to the source repo would be useful!

svn co http://liquibase.jira.com/svn/CORE/trunk

It is also on the sourceforge download page (http://sourceforge.net/projects/liquibase/files/).  I"ll add a better link to that on the liquibase download page
