+ <title>General Information</title>
+ <p>The <seealso marker="tftp#start/1">start/1</seealso> function starts
+ a daemon process listening for UDP packets on a port. When it
+ receives a request for read or write, it spawns a temporary server
+ process handling the transfer.</p>
+ <p>On the client side,
+ function <seealso marker="tftp#read_file/3">read_file/3</seealso>
+ and <seealso marker="tftp#write_file/3">write_file/3</seealso>
+ spawn a temporary client process establishing
+ contact with a TFTP daemon and perform the file transfer.</p>
+ <p><c>tftp</c> uses a callback module to handle the file
+ transfer. Two such callback modules are provided,
+ <c>tftp_binary</c> and <c>tftp_file</c>. See
+ <seealso marker="tftp#read_file/3">read_file/3</seealso> and
+ <seealso marker="tftp#write_file/3">write_file/3</seealso> for details.
+ You can also implement your own callback modules, see
+ <seealso marker="tftp#tftp_callback">CALLBACK FUNCTIONS</seealso>.
+ A callback module provided by
+ the user is registered using option <c>callback</c>, see
+ <seealso marker="tftp#options">DATA TYPES</seealso>.</p>

+ <title>Using the TFTP client and server</title>
+ <p>This is a simple example of starting the TFTP server and reading the content
+ of a sample file using the TFTP client.</p>
+
+ <p><em>Step 1.</em> Create a sample file to be used for the transfer:</p>
+ <code>
+ $ echo "Erlang/OTP 21" > file.txt
+ </code>
+
+ <p><em>Step 2.</em> Start the TFTP server:</p>
+ <code type="erl" >
+ 1> {ok, Pid} = tftp:start([{port, 19999}]).
+ <![CDATA[{ok,<0.65.0>}]]>
+ </code>
+
+ <p><em>Step 3.</em> Start the TFTP client (in another shell):</p>
+ <code type="erl" >
+ 1> tftp:read_file("file.txt", binary, [{port, 19999}]).
+ <![CDATA[{ok,<<"Erlang/OTP 21\n">>}]]>
