1//! The RFC 959 System (`SYST`) command
2//
3// This command is used to find out the type of operating
4// system at the server.  The reply shall have as its first
5// word one of the system names listed in the current version
6// of the Assigned Numbers document [4].
7//
8// This response is kind of like the User-Agent in http: very much mis-used to gauge
9// the capabilities of the other peer. D.J. Bernstein recommends to just respond with
10// `UNIX Type: L8` for greatest compatibility.
