Commit Message

Sean Anderson July 25, 2022, 3:10 p.m. UTC 
Instead of re-matching the compatible string in order to determine the init
function, just store it in the match data. The separate setup functions
aren't needed anymore. Merge their content into init as well. To ensure
everything compiles correctly, we move them to the bottom of the file.
