info_command_spawn is a specialised version of info_command. It automatically sends the command contained in the
message key to players as soon as they spawn. As of Quoth 2.2 you no longer need to terminate commands with
\n, by default the mod does this for you. If you need the old behaviour back, apply spawnflag 8 to the entity.
It also always has the RESEND_ON_LOAD flag, so the command in
message will be re-sent to players when they load a save game or when they connect to a co-op server mid game, unless the command is superseded by another info_command with the flag. See the environment variables page for more information.
Only one info_command_spawn message is allowed per map. To send multiple commands, use a single entity with a semicolon-separated list of commands.
