Generates profiles to be appended to regular import on SIMC.
Instructions are on page, but the gist is add a trinket list, copy it, and put it at the bottom of your simc import, and comment out your existing trinkets.
Use the hosted version here: https://dheighton.github.io/simc-trinket-compare/trinkets.html
Or Download and run on your local computer, needs no extra code.
