I understand upgrading from TeX Live 2012 to 2013 is not a single-click operation.
As I was working on some important documents and didn't want to compromise my TeX distribution, I've put off upgrading until now.
I'm ready now but, before installing 2013, I'd like to perform a clean uninstall of TeXLive 2012. What steps should I take? What should I look out for? I'm running Mac OS 10.8.3.
