# 下面是关于FastDHT servers 的设定 需要对FastDHT servers 有所了解,这里只说字面意思了
# 可以通过 #include filename 方式来加载 FastDHT servers  的配置,装上FastDHT就知道该如何配置啦。
# 同样要求 check_file_duplicate=1 时才有用,不然系统会忽略
# fdht_servers.conf 记载的是 FastDHT servers 列表 
# you can use "#include filename" (not include double quotes) directive to 
# load FastDHT server list, when the filename is a relative path such as 
# pure filename, the base path is the base path of current/this config file.
# must set FastDHT server list when check_file_duplicate is true / on
# please see INSTALL of FastDHT for detail
