Outline Extractor from Applied OLAP, Inc

Recently I try to find a way to compare two similar essbase outline between development version and production one. Then I found that OlapUnderground Outline Extractor is very nice tool to help me. It has the ability to export all outline member to the flat file. So All I do is just exporting two outlines, open it with an editor which can compare two files (you can use Notepad++ or UltraEdit), and figure out the difference between both files. Nice & Easy.
