# These are very much incomplete completions for the aws-cli suite.
# In addition to a complete list of services, the `aws s3` completions are mostly complete
# (and are the primary reason this file exists). The automatically generated completions
# for `aws` via `fish_update_completions` are pretty useless due to non-standard formatting.
