""" Adapter module for working with pydicom < 1.0 and >= 1.0

In what follows, "dicom is available" means we can import either a) ``dicom``

(pydicom < 1.0) or or b) ``pydicom`` (pydicom >= 1.0).

Regardless of whether dicom is available this module should be importable

without error, and always defines:

* have_dicom : True if we can import pydicom or dicom;

* pydicom : pydicom module or dicom module or None of not importable;

* read_file : ``read_file`` function if pydicom or dicom module is importable

  else None;

* tag_for_keyword : ``tag_for_keyword`` function if pydicom or dicom module

  is importable else None;

A test decorator is available in nibabel.nicom.tests:

* dicom_test : test decorator that skips test if dicom not available.

A deprecated copy is available here for backward compatibility.
