uploading the filename passed. It reads the file from input, which
can be a file-like object or a path to a local file. If a packethook
is provided, it must be a function that takes a single parameter,
which will be a copy of each DAT packet sent in the form of a
TftpPacketDAT object. The timeout parameter may be used to override
the default SOCK_TIMEOUT setting, which is the amount of time that
the client will wait for a DAT packet to be ACKd by the server.
Note: If input is a hyphen, stdin is used."""
