Tim Jenness is this good for a CLO post related to these changes?
Butler and obs_base command line scripts have changed to a single command with subcommands
hsc, butler, obspackages
The following butler scripts have been replaced with a top-level butler command, with git-style subcommands:
`dumpButlerConfig` is now `butler dump-config`
`makeButlerRepo` is now `butler create`
`validateButlerConfiguration` is now `butler validate-config`
Supported options have remained the same, but some of the names have changed with the intention of standardizing on common option names.
the ci_hsc_gen3 script `registrerInstruments` has been replaced with two commands for registering the instrument and writing the calibrations:
A list of all available `butler` subcommands is available by the standard `--help` option; `butler --help`.
The butler command is defined in `daf_butler`, but subcommand "plugins" are loaded dynamically so make sure you have `setup` the packages you intend to use before calling `butler --help` or attempting to use sub-commands.
Similarly, help for each of the subcommands is available by calling `butler <subcommand> --help`.
