Major mode for viewing an archive file in a dired-like way.
You can move around using the usual cursor motion commands.
Letters no longer insert themselves.
Type `e' to pull a file out of the archive and into its own buffer;
or click mouse-2 on the file's line in the archive mode buffer.
If you edit a sub-file of this archive (as with the `e' command) and
save it, the contents of that buffer will be saved back into the
archive.
Uses keymap `archive-mode-map', which is not currently defined.
