Good. But why dd rather than just 'cp'?  I often see examples with dd
where cp seems to work, e.g. coping a floppy image to /dev/fd0.
I dislike dd because it doesnt follow normal unix syntax. So the shell
filename completion doesnt work. Windoze isnt alone in having ugly
historical baggage.

Bonus points for the experts:
Do you know any way to create a hard link to the file, so he doesnt even
need to break the download?
