in butler (probably butlerUtils), users would like the ability to dump info from a repository's sqlite registry to text (console output). This is already implemented in obs_subaru/.../registryInfo.py, and basically just needs to be ported to butler in a sensible place. There are a few cases that assume certain columns are present and we need either to make the script more generic, or Robert Lupton suggests that maybe we need to standardize the registries.
