## A scripted headless player for the network tests (tests/test_net_lobby.gd
## starts several of these as separate processes).
##
## Args (after --): --identity <dir> --name <name> --address host:port
##   [--password p] [--stay seconds] [--result <json path>] [--forge] [--protocol n]
## Joins, stays a while noting who it saw, leaves, writes the outcome to the
## result file and quits. Gives up after 20 s whatever happens.
