Checking out source and building...

Hello:
     I am experiencing an issue where generateChangelog is throwing an exception as a result of encountering a table that has a column named 'over'.  As 'over' is a reserved keyword on SQLServer I am getting the exception shown in this user list post.  In trying to diagnose this issue myself, I am hoping to build liquibase so that I may submit a patch for this issue.  Please help!  Where can I checkout the source so that I may get on this?

Thank you!
