      Parameters
      ----------
      filename : `str`
          The file path
      errors : ``warn``, ``ignore``, ``strict``, optional
        The error handling scheme to use for handling parsing errors.
        The default is 'strict', which will raise a `~regions.CRTFRegionParserError`.
        ``warn`` will raise a `~regions.CRTFRegionParserWarning`, and ``ignore`` will do nothing
        (i.e., be silent).
  
      Returns
      -------
      regions : `list`
          Python `list` of `~regions.Region` objects.
  
      Examples
      --------
      >>> from regions import read_crtf
      >>> from astropy.utils.data import get_pkg_data_filename
      >>> file = get_pkg_data_filename('data/CRTFgeneral.crtf', package='regions.io.crtf.tests')
      >>> regs = read_crtf(file, errors='warn')
      >>> print(regs[0])

      radius: 2.3 arcsec
