+# Filename: scrub.py
+# Location: Various
+# Author: bgstack15@gmail.com
+# Startdate: 2016-09-28
+# Title: Script that Simultaneously Copies and Scrubs a Directory
+# Purpose: Prepare projects for publication by removing private information like usernames and hostnames
+# Package: Various
+# History:
+#    2016-10-03 working on batch rename files
+#    2016-10-20 added not ".tgz" in source.name
+#    2016-10-27 Fixed error when trying chmod on a symlink
+#    2016-10-31 Handle symlinks by duplicating the link and stopping there.
+#               Also separated directory, filename renaming tasks
+# Usage:
+#    Store this file with any package that gets published. Adjust scrub.txt in local directory.
+#  # First line: source directory      Second line: target directory. WILL BE OVERWRITTEN!
+#  /etc/ansible
