"""The special string to be used in configuration files to indicate that the butler root location should be used."""
"""Update a configuration root with the butler root location.
No changes are made if the special root string is not found in the configuration entry. The name of the tag is defined in the module variable `~lsst.daf.butler.core.repoRelocation.BUTLER_ROOT_TAG`.
Parameters ---------- configRoot : `str` Directory root location as specified in a configuration file. butlerRoot : `str` Butler root directory. Absolute path is inserted into the ``configRoot`` where the `~lsst.daf.butler.core.repoRelocation.BUTLER_ROOT_TAG` string is found.
Returns ------- newRoot : `str` New configuration string, with the root tag replaced with the butler root if that tag was present in the supplied configuration root.
Raises ------ ValueError Raised if ``butlerRoot`` is not set but a value is required. """
