+Command Line Interface
+----------------------
+
+.. versionadded:: 3.4
+
+The :mod:`tarfile` module provides a simple command line interface to interact
+with tar archives.
+
+If you want to create a new tar archive, specify its name after the :option:`-c`
+option and then list the filename(s) that should be included::
+
+    $ python -m tarfile -c monty.tar  spam.txt eggs.txt
+
+Passing a directory is also acceptable::
+
+    $ python -m tarfile -c monty.tar life-of-brian_1979/
+
+If you want to extract a tar archive into the current directory, use
+the :option:`-e` option::
+
+    $ python -m tarfile -e monty.tar
+
+You can also extract a tar archive into a different directory by passing the
+directory's name::
+
+    $ python -m tarfile -e monty.tar  other-dir/
+
+For a list of the files in a tar archive, use the :option:`-l` option::
+
+    $ python -m tarfile -l monty.tar
+
+
