I really wish I understood what this script is doing. To me, the article assumes the reader already knows a lot of what is being referred to.

I can write queries, but I have never used Powershell, and I can't make heads or tails out of these directions.

I do have a query with results that I would like to export to a file (although I want it tab-delimited, not comma separated), but I would need the directions to be more explanatory than this.
