.meta4-file for single specified file.
--fn NAME -- the only required option specifying file's name.
--desc "..." -- set file's description.
--mtime FILE -- let published date be equal to FILE's mtime.
--sig FILE -- path to armored OpenPGP's signature file.
--torrent URL -- set BitTorrent's URL.
+-fn NAME -- the only required option specifying file's name.

-hashes -- comma-separated list of colon-separated pairs of hash'es
name and the external command used to compute it. Command
shall take the data from stdin and print the digest in
Following hashes are predefined by default:
* sha-256:sha256 -- standardized name; standard command in many OSes
- Maybe fast on hardware accelerated CPUs
+ May be fast on hardware accelerated CPUs.
* sha-512:sha512 -- standardized name; standard command in many OSes
- Faster on 64-bit CPUs than software sha-256
+ Faster on 64-bit CPUs than software sha-256.
* skein-256:skein256 -- non-standardized name; out-of-box command in FreeBSD
- Faster than software sha-*/shake*
+ Faster than software sha-*/shake*.
* skein-512:skein512 -- non-standardized name; out-of-box command in FreeBSD
- Faster on 64-bit CPUs than skein-256
-* shake128:shake128sum -- standardized name; command is in contrib/
- Can be faster on hardware than sha-*/skein-*
-* shake256:shake256sum -- standardized name; command is in contrib/
+ Faster on 64-bit CPUs than skein-256.
+* shake128:goshake128 -- standardized name; non-standard command
+ Faster than software sha-*. Much faster on hardware.
+* shake256:goshake256 -- standardized name; non-standard command
+ Same speed as sha-512 on 64-bit CPUs.
+ Much faster on hardware.

* streebog-512:streebog512sum -- non-standardized name; command is in contrib/
* blake3-256:b3sum -- non-standardized name; additional package in most OSes
Federation's government standard. Skein is SHA3-finalist. BLAKE3 is
reduced round Merklee-tree-based BLAKE2 descendant. BLAKE2 is reduced
round BLAKE, that also was one of SHA3-finalists.

+meta4-check utility is used to check files against provided Metalink4.
+
+-extract-sig -- store the OpenPGP signature (if exists) in .asc file nearby.
+-hashes -- same as in meta4-create. Hashes are sorted by preferences
+ priority. First matching one will be used to check integrity.
