Options: -c, --conf FILE configuration file (default: h2o.conf) -m, --mode <mode> specifies one of the following mode - worker: invoked process handles incoming connections (default) - daemon: spawns a master process and exits. `error-log` must be configured when using this mode, as all the errors are logged to the file instead of being emitted to STDERR - master: invoked process becomes a master process (using the `share/h2o/start_server` command) and spawns a worker process for handling incoming connections. Users may send SIGHUP to the master process to reconfigure or upgrade the server. - test: tests the configuration and exits -t, --test synonym of `--mode=test` -v, --version prints the version number -h, --help print this help
