# For each Borg sub-command that borgmatic uses, print out the Borg flags that borgmatic does not
# appear to support yet. This script isn't terribly robust. It's intended as a basic tool to ferret
# out unsupported Borg options so that they can be considered for addition to borgmatic.
# Generate a sample borgmatic configuration with all options set, and uncomment all options.

# For each sub-command (prune, create, and check), collect the Borg command-line flags that result
# from running borgmatic with the generated configuration. Then, collect the full set of available
# Borg flags as reported by "borg --help" for that sub-command. Finally, compare the two lists of
# flags to determine which Borg flags borgmatic doesn't yet support.
