Usage:\n\
newserv [ACTION] [OPTIONS...]\n\
\n\
If ACTION is not specified, newserv runs in server mode. PSO clients can\n\
connect normally, join lobbies, play games, and use the proxy server. See\n\
README.md and system/config.json for more information.\n\
\n\
When ACTION is given, newserv will do things other than running the server.\n\
\n\
Some actions accept input and/or output filenames; see the descriptions below\n\
for details. If INPUT-FILENAME is missing or is '-', newserv reads from stdin.\n\
If OUTPUT-FILENAME is missing and the input is not from stdin, newserv writes\n\
the output to INPUT-FILENAME.dec or a similarly-named file; if OUTPUT-FILENAME\n\
is '-', newserv writes the output to stdout. If stdout is a terminal and the\n\
output is not text or JSON, the data written to stdout is formatted in a\n\
hex/ASCII view; in any other case, the raw output is written to stdout, which\n\
(for most actions) may include arbitrary binary data.\n\
\n\
The actions are:\n",
