The functions in this extension implement client access to file
servers speaking the File Transfer Protocol (FTP) as defined in
<ulink url="&url.rfc;959">&url.rfc;959</ulink>. This extension is
meant for detailed access to an FTP server providing a wide range
of control to the executing script. If you only wish to
read from or write to a file on an FTP server, consider using
the <link linkend="wrappers.ftp"><literal>ftp://</literal> wrapper</link>
with the <link linkend="ref.filesystem">filesystem functions</link>
which provide a simpler and more intuitive interface.
