-=head1 NAME
-
-Net::Cmd - Network Command class (as used by FTP, SMTP etc)
-
-=head1 SYNOPSIS
-
- use Net::Cmd;
-
- @ISA = qw(Net::Cmd);
-
-=head1 DESCRIPTION
-
-C<Net::Cmd> is a collection of methods that can be inherited by a sub class
-of C<IO::Handle>. These methods implement the functionality required for a
-command based protocol, for example FTP and SMTP.
-
-=head1 USER METHODS
-
-These methods provide a user interface to the C<Net::Cmd> object.
-
-=over 4
-
-=item debug ( VALUE )
-
-Set the level of debug information for this object. If C<VALUE> is not given
-then the current state is returned. Otherwise the state is changed to
-C<VALUE> and the previous state returned. If C<VALUE> is C<undef> then
-the debug level will be set to the default debug level for the class.
-
-This method can also be called as a I<static> method to set/get the default
-debug level for a given class.
-
-=item message ()
-
-Returns the text message returned from the last command
-
-=item code ()
-
-Returns the 3-digit code from the last command. If a command is pending
-then the value 0 is returned
-
-=item ok ()
-
-Returns non-zero if the last code value was greater than zero and
-less than 400. This holds true for most command servers. Servers
-where this does not hold may override this method.
-
-=item status ()
-
-Returns the most significant digit of the current status code. If a command
-is pending then C<CMD_PENDING> is returned.
-
-=item datasend ( DATA )
-
-Send data to the remote server, delimiting lines with CRLF. Any lin starting
-with a '.' will be prefixed with another '.'.
-
-=item dataend ()
-
-End the sending of data to the remote server. This is done by ensureing that
-the data already sent ends with CRLF then sending '.CRLF' to end the
-transmission. Once this data has been sent C<dataend> calls C<response> and
-returns true if C<response> returns CMD_OK.
-
-=back
-
-=head1 CLASS METHODS
-
-These methods are not intended to be called by the user, but used or
-over-ridden by a sub-class of C<Net::Cmd>
-
-=over 4
-
-=item debug_print ( DIR, TEXT )
-
-Print debugging information. C<DIR> denotes the direction I<true> being
-data being sent to the server. Calls C<debug_text> before printing to
-STDERR.
-
-=item debug_text ( TEXT )
-
-This method is called to print debugging information. TEXT is
-the text being sent. The method should return the text to be printed
-
-This is primarily meant for the use of modules such as FTP where passwords
-are sent, but we do not want to display them in the debugging information.
-
-=item command ( CMD [, ARGS, ... ])
-
-Send a command to the command server. All arguments a first joined with
-a space character and CRLF is appended, this string is then sent to the
-command server.
-
-Returns undef upon failure
-
-=item unsupported ()
-
-Sets the status code to 580 and the response text to 'Unsupported command'.
-Returns zero.
-
-=item responce ()
-
-Obtain a responce from the server. Upon success the most significant digit
-of the status code is returned. Upon failure, timeout etc., I<undef> is
-returned.
-
-=item parse_response ( TEXT )
-
-This method is called by C<response> as a method with one argument. It should
-return an array of 2 values, the 3-digit status code and a flag which is true
-when this is part of a multi-line response and this line is not the list.
-
-=item getline ()
-
-Retreive one line, delimited by CRLF, from the remote server. Returns I<undef>
-upon failure.
-
-B<NOTE>: If you do use this method for any reason, please remember to add
-some C<debug_print> calls into your method.
-
-=item ungetline ( TEXT )
-
-Unget a line of text from the server.
-
-=item read_until_dot ()
-
-Read data from the remote server until a line consisting of a single '.'.
-Any lines starting with '..' will have one of the '.'s removed.
-
-Returns a reference to a list containing the lines, or I<undef> upon failure.
-
-=back
-
-=head1 EXPORTS
-
-C<Net::Cmd> exports six subroutines, five of these, C<CMD_INFO>, C<CMD_OK>,
-C<CMD_MORE>, C<CMD_REJECT> and C<CMD_ERROR> ,correspond to possible results
-of C<response> and C<status>. The sixth is C<CMD_PENDING>.

+Returns a filehandle tied to the Net::Cmd object. After issuing a

+Similarly, you may write to the filehandle in order to send data to
