+    <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>
