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, the data written to stdout is formatted in a hex/ASCII\n\
view; in any other case, the raw output is written to stdout, which (for most\n\
actions) may include arbitrary binary data.\n\
\n\
The actions are:\n\
help\n\
You\'re reading it now.\n\
compress-prs [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
compress-pr2 [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
compress-bc0 [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Compress data using the PRS, PR2, or BC0 algorithms. By default, the\n\
heuristic-based compressor is used, which gives a good balance between\n\
memory usage, CPU usage, and output size. For PRS and PR2, this compressor\n\
can be tuned with the --compression-level=N option, which specifies how\n\
aggressive the compressor should be in searching for literal sequences. The\n\
default level is 0; a higher value generally means slower compression and a\n\
smaller output size. If the compression level is -1, the input data is\n\
encoded in a PRS-compatible format but not actually compressed, resulting\n\
in valid PRS data which is about 9/8 the size of the input.\n\
There is also a compressor which produces the absolute smallest output\n\
size, but uses much more memory and CPU time. To use this compressor, use\n\
the --optimal option.\n\
decompress-prs [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
decompress-pr2 [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
decompress-bc0 [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Decompress data compressed using the PRS, PR2, or BC0 algorithms.\n\
recompress-prs-optimal [INPUT-AND-OUTPUT-FILENAME]\n\
Recompress the input PRS file optimally, overwriting it with the optimally-\n\
compressed result.\n\
prs-size [INPUT-FILENAME]\n\
Compute the decompressed size of the PRS-compressed input data, but don\'t\n\
write the decompressed data anywhere.\n\
disassemble-prs [INPUT-FILENAME]\n\
disassemble-bc0 [INPUT-FILENAME]\n\
Write a textual representation of the commands contained in a PRS or BC0\n\
command stream. The output is written to stdout. This is mainly useful for\n\
debugging the compressors and decompressors themselves.\n\
encrypt-data [INPUT-FILENAME [OUTPUT-FILENAME] [OPTIONS...]]\n\
decrypt-data [INPUT-FILENAME [OUTPUT-FILENAME] [OPTIONS...]]\n\
Encrypt or decrypt data using PSO\'s standard network protocol encryption.\n\
By default, PSO V3 (GameCube/XBOX) encryption is used, but this can be\n\
overridden with the --pc or --bb options. The --seed=SEED option specifies\n\
the encryption seed (4 hex bytes for PC or GC, or 48 hex bytes for BB). For\n\
BB, the --key=KEY-NAME option is required as well, and refers to a .nsk\n\
file in system/blueburst/keys (without the directory or .nsk extension).\n\
For non-BB ciphers, the --big-endian option applies the cipher masks as\n\
big-endian instead of little-endian, which is necessary for some GameCube\n\
file formats.\n\
encrypt-trivial-data --seed=BASIS [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
decrypt-trivial-data [--seed=BASIS] [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Encrypt or decrypt data using the Episode 3 trivial algorithm. When\n\
encrypting, --seed=BASIS is required; BASIS should be a single byte\n\
specified in hexadecimal. When decrypting, BASIS should be specified the\n\
same way, but if it is not given, newserv will try all possible basis\n\
values and return the one that results in the greatest number of zero bytes\n\
in the output.\n\
encrypt-challenge-data [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
decrypt-challenge-data [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Encrypt or decrypt data using the challenge mode trivial algorithm.\n\
encrypt-pc-save --seed=SEED [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
decrypt-pc-save --seed=SEED [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Encrypt or decrypt a PSO PC character file (PSO______SYS or PSO______SYD)\n\
or Guild Card file (PSO______GUD). SEED should be the serial number\n\
associated with the save file, as a 32-bit hexadecimal integer.\n\
encrypt-gci-save CRYPT-OPTION INPUT-FILENAME [OUTPUT-FILENAME]\n\
decrypt-gci-save CRYPT-OPTION INPUT-FILENAME [OUTPUT-FILENAME]\n\
Encrypt or decrypt a character or Guild Card file in GCI format. If\n\
encrypting, the checksum is also recomputed and stored in the encrypted\n\
file. CRYPT-OPTION is required; it can be either --sys=SYSTEM-FILENAME\n\
(specifying the name of the corresponding PSO_SYSTEM .gci file) or\n\
--seed=ROUND1-SEED (specified as a 32-bit hexadecimal number).\n\
salvage-gci INPUT-FILENAME [--round2] [CRYPT-OPTION] [--bytes=SIZE]\n\
Attempt to find either the round-1 or round-2 decryption seed for a\n\
corrupted GCI file. If --round2 is given, then CRYPT-OPTION must be given\n\
(and should specify either a valid system file or the round1 seed).\n\
find-decryption-seed OPTIONS...\n\
Perform a brute-force search for a decryption seed of the given data. The\n\
ciphertext is specified with the --encrypted=DATA option and the expected\n\
plaintext is specified with the --decrypted=DATA option. The plaintext may\n\
include unmatched bytes (specified with the Phosg parse_data_string ?\n\
operator), but overall it must be the same length as the ciphertext. By\n\
default, this option uses PSO V3 encryption, but this can be overridden\n\
with --pc. (BB encryption seeds are too long to be searched for with this\n\
function.) By default, the number of worker threads is equal to the number\n\
of CPU cores in the system, but this can be overridden with the\n\
--threads=NUM-THREADS option.\n\
decode-sjis [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Apply newserv\'s text decoding algorithm to the input data, producing\n\
little-endian UTF-16 output data.\n\
decode-gci INPUT-FILENAME [OPTIONS...]\n\
decode-vms INPUT-FILENAME [OPTIONS...]\n\
decode-dlq INPUT-FILENAME\n\
decode-qst INPUT-FILENAME\n\
Decode the input quest file into a compressed, unencrypted .bin or .dat\n\
file (or in the case of decode-qst, both a .bin and a .dat file).\n\
INPUT-FILENAME must be specified, but there is no OUTPUT-FILENAME; the\n\
output is written to INPUT-FILENAME.dec (or .bin, or .dat). If the output\n\
is a .dec file, you can rename it to .bin or .dat manually. DLQ and QST\n\
decoding are relatively simple operations, but GCI and VMS decoding can be\n\
computationally expensive if the file is encrypted and doesn\'t contain an\n\
embedded seed. If you know the player\'s serial number who generated the\n\
GCI or VMS file, use the --seed=SEED option and give the serial number (as\n\
a hex-encoded 32-bit integer). If you don\'t know the serial number,\n\
newserv will find it via a brute-force search, which will take a long time.\n\
encode-qst INPUT-FILENAME [OUTPUT-FILENAME] [OPTIONS...]\n\
Encode the input quest file (in .bin/.dat format) into a .qst file. If\n\
--download is given, generates a download .qst instead of an online .qst.\n\
Specify the quest\'s game version with one of the --dc-nte, --dc-v1,\n\
--dc-v2, --pc, --gc-nte, --gc, --gc-ep3, --xb, or --bb options.\n\
disassemble-quest-script [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Disassemble the input quest script (.bin file) into a text representation\n\
of the commands and metadata it contains. Specify the quest\'s game version\n\
with one of the --dc-nte, --dc-v1, --dc-v2, --pc, --gc-nte, --gc, --gc-ep3,\n\
--xb, or --bb options.\n\
cat-client ADDR:PORT\n\
Connect to the given server and simulate a PSO client. newserv will then\n\
print all the received commands to stdout, and forward any commands typed\n\
into stdin to the remote server. It is assumed that the input and output\n\
are terminals, so all commands are hex-encoded. The --patch, --dc, --pc,\n\
--gc, and --bb options can be used to select the command format and\n\
encryption. If --bb is used, the --key=KEY-NAME option is also required (as\n\
in decrypt-data above).\n\
show-ep3-maps\n\
Print the Episode 3 maps from the system/ep3 directory in a (sort of)\n\
human-readable format.\n\
show-ep3-cards\n\
Print the Episode 3 card definitions from the system/ep3 directory in a\n\
human-readable format.\n\
describe-item DATA\n\
Print the name of the item given by DATA (in hex). DATA must not contain\n\
spaces. If DATA is 20 bytes, newserv assumes it contains an unused item ID\n\
field; if it is fewer bytes, up to 16 bytes are used.\n\
encode-item DESCRIPTION [--pc|--bb]\n\
Encode the description of an item into its corresponding ItemData (hex)\n\
representation. If DESCRIPTION contains spaces, it must be quoted, such as\n\
\"L&K14 COMBAT +10 0/10/15/0/35\".\n\
replay-log [INPUT-FILENAME] [OPTIONS...]\n\
Replay a terminal log as if it were a client session. input-filename may be\n\
specified for this option. This is used for regression testing, to make\n\
sure client sessions are repeatable and code changes don\'t affect existing\n\
(working) functionality.\n\
extract-afs [INPUT-FILENAME] [--big-endian]\n\
extract-gsl [INPUT-FILENAME] [--big-endian]\n\
extract-bml [INPUT-FILENAME] [--big-endian]\n\
Extract all files from an AFS, GSL, or BML archive into the current\n\
directory. input-filename may be specified. If output-filename is\n\
specified, then it is treated as a prefix which is prepended to the\n\
filename of each file contained in the archive. If --big-endian is given,\n\
the archive header is read in GameCube format; otherwise it is read in\n\
PC/BB format.\n\
decode-text-archive [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
encode-text-archive [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Decode a text archive (e.g. TextEnglish.pr2) to JSON for easy editing, or\n\
encode a JSON file to a text archive.\n\
decode-unicode-text-set [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
encode-unicode-text-set [INPUT-FILENAME [OUTPUT-FILENAME]]\n\
Decode a Unicode text set (e.g. unitxt_e.prs) to JSON for easy editing, or\n\
encode a JSON file to a Unicode text set.\n\
convert-rare-item-set INPUT-FILENAME [OUTPUT-FILENAME]\n\
If OUTPUT-FILENAME is not given, print the contents of a rare item table in\n\
a human-readable format. Otherwise, convert the input rare item set to a\n\
different format and write it to OUTPUT-FILENAME. Both filenames must end\n\
in one of the following extensions:\n\
.json (newserv JSON rare item table)\n\
.gsl (PSO BB little-endian GSL archive)\n\
.gslb (PSO GC big-endian GSL archive)\n\
.afs (PSO V2 little-endian AFS archive)\n\
.rel (Schtserv rare table; cannot be used in output filename)\n\
generate-dc-serial-number [--domain=DOMAIN] [--subdomain=SUBDOMAIN]\n\
Generate a PSO DC serial number. DOMAIN should be 0 for Japanese, 1 for\n\
USA, or 2 for Europe. SUBDOMAIN should be 0 for v1, or 1 for v2.\n\
generate-all-dc-serial-numbers\n\
Generate all possible PSO DC serial numbers.\n\
inspect-dc-serial-number SERIAL-NUMBER\n\
Show which domain and subdomain the serial number belongs to. (As with\n\
generate-dc-serial-number, described above, this will tell you which PSO\n\
version it is valid for.)\n\
dc-serial-number-speed-test\n\
Run a speed test of the two DC serial number validation functions.\n\
\n\
A few options apply to multiple modes described above:\n\
--parse-data\n\
For modes that take input (from a file or from stdin), parse the input as\n\
a hex string before encrypting/decoding/etc.\n\
--config=FILENAME\n\
Use this file instead of system/config.json.\n\
