Etch: emacs or emac21?

[Rodolfo Medina <rodolfo.medina@gmail.com>]

Hi, Debian users.

In Sarge there was only the package `emacs21'.  Now in Etch we have also
`emacs', but the difference between the two is not clear to me.  What should I
install in order to use the Emacs editor, `emacs' or `emacs21'?

Thanks for any reply
