This tool is available to the community for free, but I kindly request if you see the value in time this tool saves you, that you donate whatever you can to help me pay off student loans. 

Every donation helps immensely.  I do however understand that we’re all in this mess somehow and I understand if you aren’t able to donate at this time.  To donate simply click the “Donate!” button on the script.  I am suggesting $10 for an individual, but whatever you can spare will insure the future development of this script and updates.
