* libmscp is follows:
*
* 1. create mscp instance with mscp_init()
* 2. connect to remote host with mscp_connect()
* 3. add path to source files with mscp_add_src_path()
* 4. set path to destination with mscp_set_dst_path()
* 5. start to scan source files with mscp_scan()
* 6. start copy with mscp_start()
* 7. wait for copy finished with mscp_join()
* 8. cleanup mscp instance with mscp_cleanup() and mscp_free()
* 2. set remote host and copy direction with mscp_set_remote()
