+  <modulesummary>A File Transfer Protocol client.</modulesummary>
+
+  <description>
+
+    <p>This module implements a client for file transfer
+      according to a subset of the File Transfer Protocol (FTP), see
+    <url href="http://www.ietf.org/rfc/rfc959.txt">RFC 959</url>.</p>
+
+    <p>As from <c>Inets</c> 4.4.1, the FTP
+      client always tries to use passive FTP mode and only resort
+      to active FTP mode if this fails. This default behavior can be 
+      changed by start option <seealso marker="#mode">mode</seealso>.</p>
+
+    <marker id="two_start"></marker>
+
+    <p>An FTP client can be started in two ways. One is using the 
+      <seealso marker="#service_start">Inets service framework</seealso>,
+      the other is to start it directly as a standalone process 
+      using function <seealso marker="#open">open</seealso>.</p>
+
+    <p>For a simple example of an FTP session, see 
+      <seealso marker="ftp_client">Inets User's Guide</seealso>.</p>
+
+    <p>In addition to the ordinary functions for receiving and sending
+      files (see <c>recv/2</c>, <c>recv/3</c>, <c>send/2</c>, and
+      <c>send/3</c>) there are functions for receiving remote files as
+      binaries (see <c>recv_bin/2</c>) and for sending binaries to be
+      stored as remote files (see <c>send_bin/3</c>).</p>
+
+    <p>A set of functions is provvided for sending and receiving
+      contiguous parts of a file to be stored in a remote file. For send,
+      see <c>send_chunk_start/2</c>, <c>send_chunk/2</c>, and
+      <c>send_chunk_end/1</c>. For receive, see
+      <c>recv_chunk_start/2</c> and <c>recv_chunk/</c>).</p>
+
+    <p>The return values of the following functions depend
+      much on the implementation of the FTP server at the remote
+      host. In particular, the results from <c>ls</c> and <c>nlist</c>
+      varies. Often real errors are not reported as errors by <c>ls</c>,
+      even if, for example, a file or directory does not
+      exist. <c>nlist</c> is usually more strict, but some
+      implementations have the peculiar behaviour of responding with an
+      error if the request is a listing of the contents of a directory
+      that exists but is empty.</p>

+
+  <section>
+    <title>FTP CLIENT SERVICE START/STOP</title>
+    
+    <p>The FTP client can be started and stopped dynamically in runtime by
+      calling the <c>Inets</c> application API 
+      <c>inets:start(ftpc, ServiceConfig)</c>,
+      or <c>inets:start(ftpc, ServiceConfig, How)</c>, and
+      <c>inets:stop(ftpc, Pid)</c>. 
+      For details, see <seealso marker="inets">inets(3)</seealso>.</p>
+
+    <p>The available configuration options are as follows:</p>

+	<p>With <c>inet6fb4</c> the client behaves as before, that is, 
+	  tries to use IPv6, and only if that does not work it
+          uses IPv4).</p>
+	<p>Default is <c>inet</c> (IPv4).</p>

+	<p>Data connect time-out. 
+	The time the client waits for the server to connect to the 
+	data socket.</p>

+

+	<p><c>InitProgress = term()</c></p>
+	<p>Default is <c>ignore</c>.</p>
+      </item>  
+
+    </taglist>
+  
+    <p>Option <c>progress</c> is intended to be used by applications that
+      want to create some type of progress report, such as a progress bar in
+      a GUI. Default for the progress option is <c>ignore</c>,
+      that is, the option is not used. When the progress option is
+      specified, the following happens when <c>ftp:send/[3,4]</c> or
+      <c>ftp:recv/[3,4]</c> are called:</p>
+    
+    <list type="bulleted">
+      <item>
+	<p>Before a file is transferred, the following call is
+	  made to indicate the start of the file transfer and how large
+	  the file is. The return value of the callback function
+	  is to be a new value for the <c>UserProgressTerm</c> that will
+	  be used as input the next time the callback function is
+	  called.</p>
+	<p><c>
+	  CBModule:CBFunction(InitProgress, File, {file_size, FileSize})
+	</c></p>
+      </item>
+      
+      <item>
+	<p>Every time a chunk of bytes is transferred the
+	  following call is made:</p>
+	<p><c>
+	    CBModule:CBFunction(UserProgressTerm, File, {transfer_size, TransferSize})
+        </c></p>
+      </item>
+
+      <item>
+	<p>At the end of the file the following call is
+	  made to indicate the end of the transfer:</p>
+	<p><c>
+	    CBModule:CBFunction(UserProgressTerm, File, {transfer_size, 0})      
+	</c></p>
+      </item>
+    </list>
+    
+    <p>The callback function is to be defined as follows:</p>
+
+    <p><c>
+	CBModule:CBFunction(UserProgressTerm, File, Size) -> UserProgressTerm
+    </c></p>
+    
+    <p><c>
+	CBModule = CBFunction = atom()
+      </c></p>
+
+    <p><c>
+	UserProgressTerm = term()
+      </c></p>
+
+    <p><c>
+	File = string()
+      </c></p>
+
+    <p><c>
+	Size = {transfer_size, integer()} | {file_size, integer()} | {file_size, unknown}
+    </c></p>
+    
+    <p>For remote files, <c>ftp</c> cannot determine the
+      file size in a platform independent way. In this case the size
+      becomes <c>unknown</c> and it is left to the application to
+      determine the size.</p>
+    
+    <note>
+      <p>The callback is made by a middleman process, hence the
+	file transfer is not affected by the code in the progress
+	callback function. If the callback crashes, this is
+	detected by the FTP connection process, which then prints an
+	info-report and goes on as if the progress option was set
+	to <c>ignore</c>.</p>
+    </note>
+    
+    <p>The file transfer type is set to the default of the FTP server
+      when the session is opened. This is usually ASCCI mode.
+    </p>
+    
+    <p>The current local working directory (compare <c>lpwd/1</c>) is set 
+      to the value reported by <c>file:get_cwd/1</c>, the wanted
+      local directory.
+    </p>
+    
+    <p>The return value <c>Pid</c> is used as a reference to the
+      newly created FTP client in all other functions, and they are to
+      be called by the process that created the connection. The FTP
+      client process monitors the process that created it and
+      terminates if that process terminates.</p>

+    <title>Getting Started</title>
+
+    <p>FTP clients are considered to be rather temporary. Thus, 
+      they are only started and stopped during runtime and cannot 
+      be started at application startup.
+      The FTP client API is designed to allow some functions to 
+      return intermediate results. This implies that only the process
+      that started the FTP client can access it with
+      preserved sane semantics. 
+      If the process that started the FTP session 
+      dies, the FTP client process terminates.</p>
+
+    <p>The client supports IPv6 as long as the underlying mechanisms
+      also do so.</p>
+
+    <p>The following is a simple example of an FTP session, where
+      the user <c>guest</c> with password <c>password</c> logs on to
+      the remote host <c>erlang.org</c>:</p>
+    <code type="erl"><![CDATA[
+      1> inets:start().
+      ok
+      2> {ok, Pid} = inets:start(ftpc, [{host, "erlang.org"}]).
+      {ok,<0.22.0>}
+      3> ftp:user(Pid, "guest", "password").
+      ok
+      4> ftp:pwd(Pid).
+      {ok, "/home/guest"}
+      5> ftp:cd(Pid, "appl/examples").
+      ok
+      6> ftp:lpwd(Pid).
+      {ok, "/home/fred"}.
+      7> ftp:lcd(Pid, "/home/eproj/examples").
+      ok
+      8> ftp:recv(Pid, "appl.erl").
+      ok
+      9> inets:stop(ftpc, Pid).
+      ok
+    ]]></code>
+    <p> The file
+      <c>appl.erl</c> is transferred from the remote to the local
+      host.  When the session is opened, the current directory at
+      the remote host is <c>/home/guest</c>, and <c>/home/fred</c>
+      at the local host. Before transferring the file, the current
+      local directory is changed to <c>/home/eproj/examples</c>, and
+      the remote directory is set to
+      <c>/home/guest/appl/examples</c>.</p>
