$0 <command> [options] 
Commands working with config file:
  -startjob                 run job based on --conf or --qpkg
  -stopjob                  stop job based on --conf or --qpkg
Commands working with config file or standalone:
  -sendfile <src> <dst>     send specific file to server.
  -recvfile <src> <dst>     recv specific file from server.
  -senddir <src> <dst>      send specific dir to server.
  -recvdir <src> <dst>      recv specific dir from server.
  -sendlist <content_file>  send files listed in 'content_file' to server.
  -recvlist <content_file>  recv files listed in 'content_file' from server.

Options:
  All options must be given in either a config file, or by keywords, 
  All options have their own default value, if config file not exist or not given.
  * Given in config file:
    --qpkg <job_id>     use HBS QPKG's RR2 config, must be with job_id. 
    --conf <filepath>   specify job's config file path, default is none 
                        (it means must be given by keywords)
  
  * Given by keywords (will overwrite the value in config file if given),
    the following are sorted by alphabet: 
    --ip <ip>           server ip address, 
                        default is 'localhhost', means local sync.
    --logdir <folder>   specify log and statistics folder path, 
                        default will create 'logs' sub-dir under the current working dir.  
    --port <port_num>   server port number.
                        default is 8898.
    --pwd <password>    handler_login password (plain text),
                        default is "".
    --uname <user_name> handler_login user name.
                        default is empty string, it means to use server's pwd, not NAS accout's pwd.
    --way <seq|thd|proc>  run job by sequential/multi-threads/multi-proceses. it is only useful 
                        for folder-related operations. 
                        default is 'proc'.    
    --waynum <num>      the number of threads or processes, 
                        If running by 'req', this value will be ignred.
                        If running by 'thd', default value is 10.
                        If running by 'proc', default avlue is -1, it means to auto-detect the 
                        number of processor.  
	--debug             print debug message on console
Examples:
  Start a job with job_id:
    $0 -startjob --qpkg jid_001 
  Start a job with config:
    $0 -startjob --conf \"/share/Public/testrr2/job.json\"
