-# This library is no longer being maintained, and is included for backward
-# compatibility with Perl 4 programs which may require it.
-#
-# In particular, this should not be used as an example of modern Perl
-# programming techniques.
-#
-# Suggested alternative: Net::FTP
-#
-# This is a wrapper to the chat2.pl routines that make life easier
-# to do ftp type work.
-# Mostly by Lee McLoughlin <lmjm@doc.ic.ac.uk>
-# based on original version by Alan R. Martello <al@ee.pitt.edu>
-# And by A.Macpherson@bnr.co.uk for multi-homed hosts
