-- Driver: hosts a real 2-player tournament against a real running
-- pokeserver, paired with tournament_guest_test.lua running in a second
-- LOVE process. Coordinates over a shared code file (TOURNEY_CODE_FILE)
-- since the two processes have no other way to talk before the code
-- exists. The default tournament rule is exactly 3 Pokemon, so this
-- overwrites whatever party the identity actually has with 3 fixed mons
-- -- a tournament match never touches the real save (clamped copies, same
-- as any other link battle), so clobbering it here for the test is safe.
