Changes

Using the Butler

This module provides an abstracted data access interface, known as the Butler. It can be used to read and write data without having to know the details of file formats or locations.

Concrete Storage Classes

Butler Command-Line Reference

Design and Development

lsst.daf.butler is developed at https://github.com/lsst/daf_butler. You can find Jira issues for this module under the daf_butler component.
