non-interactive extracting the contents of a tar-file

[Klaus Berndl]

I know tar-mode and it displays a dired-like listing of the contents.
So the user can mark entries and extrakt them to a buffer...

What i want is the following:
Is it possible with tar-mode (or other already existing elisp-code), to
extract the full contents of a tar-file to a certain directory (or at least to
default-directory)?

Ciao,
Klaus
