These are Excel spreadsheets created by @Blanchae. I figured I'd post them here since I haven't seen him around in a while, and I don't want to lose them. Documentation can be found on his website.
It's an Excel sheet inside a ZIP since Xenforo wouldn't let me just upload a .xlsx.
FYI - You may need to change the context mentioned in the trunk configuration to suit your needs. If you want both boxes to be able to call each other's extensions as if they were one big system, use from-internal. Otherwise, from-trunk should do.
