#
# 1) first start rvc-rft in reciever mode 
#      ./rvc-rft recv (reciever hostname) (port no.) (path/to/save/file/as)
# 2) then transmit the remote file
#      ./rvc-rft send (reciever hostname) (port no.) (path/to/file)
# 3) have patience and DONE!! cuz no progress bars, etc
#    add if u want... but costly over remote shells
