I corrected the LDM links.
DM-4683 and DM-5091 were developed in parallel. One did not block the other, but since I had to write about butler in the LDM I figured I'd write about the soon-to-be current (now current) implementation.
Sorry for no description in this ticket.
Tim Jenness Also I'm sorry for not making it easy for you. Figuring out how to use all the correct channels and checkboxes to receive a feature request, gather consensus, design, implement, and submit code in LSST is also not easy. I'm doing the best I can figure out. Thanks for bearing with me.
