+wxFTP can be used to establish a connection to an FTP server and perform all the
+usual operations. Please consult the RFC 959 for more details about the FTP
+protocol.
+
+To use a commands which doesn't involve file transfer (i.e. directory oriented
+commands) you just need to call a corresponding member function or use the
+generic \helpref{SendCommand}{wxftpsendcommand} method. However to actually
+transfer files you just get or give a stream to or from this class and the
+actual data are read or written using the usual stream methods.
+
+Example of using wxFTP for file downloading:
+
+\begin{verbatim}
+    wxFTP ftp;
+
+    // if you don't use these lines anonymous login will be used
+    ftp.SetUser("user");
+    ftp.SetPassword("password");
+
+    if ( !ftp.Connect("ftp.wxwindows.org") )
+    {
+        wxLogError("Couldn't connect");
+        return;
+    }
+
+    ftp.ChDir("/pub");
+    wxInputStream *in = ftp.GetInputStream("wxWindows-4.2.0.tar.gz");
+    if ( !in )
+    {
+        wxLogError("Coudln't get file");
+    }
+    else
+    {
+        size_t size = in->StreamSize();
+        char *data = new char[size];
+        if ( !in->Read(data, size) )
+        {
+            wxLogError("Read error");
+        }
+        else
+        {
+            // file data is in the buffer
+            ...
+        }
+
+        delete [] data;
+        delete in;
+    }
+\end{verbatim}
+
+To upload a file you would do (assuming the connection to the server was opened
+successfully):
+
+\begin{verbatim}
+        wxOutputStream *out = ftp.GetOutputStream("filename");
+        if ( out )
+        {
+            out->Write(...); // your data
+            delete out;
+        }
+\end{verbatim}
+
+\wxheading{Constants}
+
+wxFTP defines constants corresponding to the two supported transfer modes:
+
+\begin{verbatim}
+enum TransferMode
+{
+    ASCII,
+    BINARY
+};
+\end{verbatim}
