The ncftp program is no longer part of the default system - it has been
replaced by a library (/usr/src/lib/libftpio) and a more powerful program
which uses it called ``fetch'' (/usr/src/usr.bin/fetch). You may find
ncftp as part of the ports collection (in /usr/ports/net/ncftp) if you
still wish to use it, though fetch is slightly more capable in that
it can fetch from both FTP and HTTP servers (ftp://... or http://... URLs).
See the man page for more details.
