Audio Convert script does not include codecs as dependencies or recommendations

This is a nice package, simple enough to install, but unusable by less technically aware people.
The package installs without checking for any installed codecs, so the script is useless on a normal install of Jaunty.

One has to read the content of the script itself and install the mentioned dependencies, some of which have changed names since the script was created in 2005 (id3tag to id3tools for instance).

Expected behaviour: Install package, right click on songs, choose nautilus-scripts>Audio Convert, choose output format and be done.
What happens: Choosing Audio Convert doesn't do anything but tell you you the operation can not be done.

A simple solution would be to just set as recommendations or dependencies the codecs, or warn the user they will need the proper codecs to encode to a given format and offer them the opportunity to install said codecs. Might pose some legal problems though.
