+#* Script Name: Add Subnets 
+#* Created: [11/31/2010] 
+#* Author: Jerry Martin 
+#* Company: The Home Depot 
+#* Email: [email protected] 
+#* Web: http://www.homedepot.com 
+#* Powershell Version: 2.0 
+#* Reqrmnts: Microsoft Active Directory Module 
+#* Keywords: 
+#*============================================================================= 
+#* Purpose:  This script was created to import a list of subnets from a CSV 
+#* File into Active Directory, Directory Services Site and Services Module. 
+#* This automates the process of creating Subnets and is intended to be used 
+#* in conjuction with the Add-SiteLinks, Add-Sites and Get-SitesAndServices 
+#* Scripts. 
+#*============================================================================= 
+
+#*============================================================================= 
+#* Usage. 
+#*============================================================================= 
+#* The parameters for this script are 
+#*        -InputCSV "Path to CSV File" Default is ".\Subnets.csv" 
+#*        -LogFile "Path to Log File" Default is ".\Logfile.txt" 
+#*        -NewLog Y/N  Defaults to N, enter Y to create a new log file 
+#* 
+#* Typical Usage would look like the following... 
+#* .\Add-Subnets.ps1 -InputCSV .\Subnetlist2.csv -Logfile C:\Logfile.txt 
+#*   OR 
+#* .\Add-Subnets.ps1  
+#* Without using the Parameters the script will use the default file locations 
+#* for the Input CSV file and Log File, and will append to the existing log.
