osm2pgsql command-line switches ---are they documented somewhere?

I’ve looked (not exhaustively) through the osm documentation and osm2pgsql on github, and searched on both “switches” and “options” without success. I can find mentions of some of them, but no comprehensive list. It seems as though there should be a list of the switches and their functions readily visible in the wiki since osm2pgsql is fairly important, but I can’t find it if it exists.

Never mind. I must have been more tired than I thought.
