// This file is newserv's canonical reference of the PSO client/server protocol.
// For the unfamiliar, the le_uint and be_uint types (from phosg/Encoding.hh)
// are the same as normal uint types, but are explicitly little-endian or
// big-endian. The parray and ptext types (from Text.hh) are the same as
// standard arrays, but have various safety and convenience features so we don't
// have to use easy-to-mess-up functions like memset/memcpy and strncpy.
// Struct names are like [S|C|SC]_CommandName_[Versions]_Numbers
// S/C denotes who sends the command (S = server, C = client, SC = both)
// If versions are not specified, the format is the same for all versions.
// For variable-length commands, generally a zero-length array is included on
// the end of the struct if the command is received by newserv, and is omitted
// if it's sent by newserv. In the latter case, we often use StringWriter to
// construct the command data instead.
// Structures are sorted by command number. Long BB commands are placed in order
// according to their low byte; for example, command 01EB is in position as EB.
// This is the format of newserv's security data, which we call the client
// config. This data is opaque to the client, so this structure is not
// technically part of the PSO protocol. Because it is opaque to the client, we
// can use the server's native-endian types instead of being explicit as we do
// for all the other structs in this file.
