Where does this mp3info come from?  I installed mp3info from
http://ruby-mp3info.rubyforge.org/ following Carlo's lead, but it
doesn't seem to have a command line component.

But looking at an example of the podcast I need to handle, in both mp3
and aac format, neither seems to have any duration related tags.

So I guess I need to figure out if there's any way to compute the duration.

Any ideas anyone?
