Tags aren't available that early!
Your mom also "wasn't available," but that didn't stop us last night.

A lot of reading, and a little bit of black magic. You know, measure twice, cut once.
Is this an April Fools' joke?
The best jokes are completely true. This is one of those.
How do I use this?
Include this mod as an "include" (the whole library is 16KiB, of which 4KiB is the icon) and call an accessor on blue.endless.earlytags.EarlyTags. The EarlyTag object you get can then do membership tests with contains. Everything is by Identifier since items and blocks probably won't exist yet.
