+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+Since Python 3.4, `pathlib <https://docs.python.org/3/library/pathlib.html>`_ has been
+included in the Python standard library. Path objects provide a simple
+and delightful way to interact with the file system. The pandas-path package enables the
+Path API for pandas through a custom accessor ``.path``. Getting just the filenames from
+a series of full file paths is as simple as ``my_files.path.name``. Other convenient operations like
+joining paths, replacing file extensions, and checking if files exist are also available.
