# This script helped with the software key (Microsoft) audit. It converts
# the multiple text files from "keyfinder.exe" to one cvs format file that
# is imported in to a spreadsheet and edited manually for clarity. I still
# had to hand remove a couple lines after running this script. This script
# was aimed at 98% success.

I know, I know. It is a lame script. It works for the most part. It converts a bunch of multiple line text files in to a single CVS (comma delimited) file for import in to a spreadsheet.
