\section{\class{wxFTP}}\label{wxftp}
+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}

+
+The default value of the user name is "anonymous".
+
+\wxheading{Remark}
+
+This parameter can be included in a URL if you want to use the URL manager.

-Returns TRUE, if successful.
+This parameter can be included in a URL if you want to use the URL manager.

+\membersection{wxFTP::GetDirList}\label{wxftpgetdirlist}
+
+\func{bool}{GetDirList}{\param{wxArrayString\& }{files}, \param{const wxString\&}{ wildcard = ""}}
+
+The GetList function is quite low-level. It returns the list of the files in
+the current directory. The list can be filtered using the {\it wildcard} string.
+If {\it wildcard} is empty (default), it will return all files in directory.
+
+The form of the list can change from one peer system to another. For example,
+for a UNIX peer system, it will look like this:
+
+\begin{verbatim}

+\end{verbatim}
+
+But on Windows system, it will look like this:
+
+\begin{verbatim}
+winamp~1 exe 520196 02-25-1999 19:28 winamp204.exe
+ 1 file(s) 520 196 bytes

+
+\membersection{wxFTP::GetFilesList}\label{wxftpgetfileslist}
+
+\func{bool}{GetFilesList}{\param{wxArrayString\& }{files}, \param{const wxString\&}{ wildcard = ""}}
+
+This function returns the computer-parsable list of the files in the current
+directory (optionally only of the files matching the {\it wildcard}, all files
+by default). This list always has the same format and contains one full
+(including the directory path) file name per line.
+
+Return value: TRUE if the file list was successfully retrieved, FALSE
+otherwise.

+Initializes an output stream to the specified {\it file}. The returned

\wxheading{Return value}
An initialized write-only stream.

+% ----------------------------------------------------------------------------
+
+\membersection{wxFTP::GetInputStream}\label{wxftpgetinput}
+
+\func{wxInputStream *}{GetInputStream}{\param{const wxString\&}{ path}}
+
+Creates a new input stream on the the specified path. You can use all but the seek
+functionality of wxStream. Seek isn't available on all streams. For example,
+http or ftp streams do not deal with it. Other functions like Tell
+are not available for this sort of stream, at present.
+You will be notified when the EOF is reached by an error.
+
+\wxheading{Return value}
+
+Returns NULL if an error occurred (it could be a network failure or the fact
+that the file doesn't exist).
+
+Returns the initialized stream. You will have to delete it yourself when you
+don't need it anymore. The destructor closes the DATA stream connection but
+will leave the COMMAND stream connection opened. It means that you can still
+send new commands without reconnecting.
+
+\wxheading{Example of a standalone connection (without wxURL)}
+
+\begin{verbatim}
+ wxFTP ftp;
+ wxInputStream *in_stream;
+ char *data;

+ ftp.Connect("a.host.domain");

+ in_stream->Read(data, in_stream->StreamSize());
