ftp with perl

Written on September 11, 2003

#!/usr/bin/perl -w

# Yet another time when dependence on libraries bit me, I had to see if
# I could manage an ftp script using the core perl libraries, so I wasn\'t
# dependent on Net::FTP being present in the same form on the system.
# This is just my proof of concept, developed with telnet and the perl
# cookbook.
