IIS Log Management Script in Powershell

IIS logs on a busy webserver can use up a lot of disk space. I wrote this little powershell script that I schedule to run on all of my web servers. It goes in and deletes out any IIS logs older than 1 year. Then it compresses any IIS logs that are left which are older than 1 day and are not already compressed. You can change the length of time for these to suit your needs by changeing the numbers in the "AddDays(-123)" parts of the script. Just make sure it's a negative number, or else you won't have any logs left.
