| #:  * `audit` [`--strict`] [`--fix`] [`--online`] [`--new-formula`] [`--display-cop-names`] [`--display-filename`] [`--only=`<method>|`--except=`<method>] [`--only-cops=`<cops>|`--except-cops=`<cops>] [<formulae>]:
 | |
| #:    Check <formulae> for Homebrew coding style violations. This should be
 | |
| #:    run before submitting a new formula.
 | |
| #:
 | |
| #:    If no <formulae> are provided, all of them are checked.
 | |
| #:
 | |
| #:    If `--strict` is passed, additional checks are run, including RuboCop
 | |
| #:    style checks.
 | |
| #:
 | |
| #:    If `--fix` is passed, style violations will be
 | |
| #:    automatically fixed using RuboCop's auto-correct feature.
 | |
| #:
 | |
| #:    If `--online` is passed, additional slower checks that require a network
 | |
| #:    connection are run.
 | |
| #:
 | |
| #:    If `--new-formula` is passed, various additional checks are run that check
 | |
| #:    if a new formula is eligible for Homebrew. This should be used when creating
 | |
| #:    new formulae and implies `--strict` and `--online`.
 | |
| #:
 | |
| #:    If `--display-cop-names` is passed, the RuboCop cop name for each violation
 | |
| #:    is included in the output.
 | |
| #:
 | |
| #:    If `--display-filename` is passed, every line of output is prefixed with the
 | |
| #:    name of the file or formula being audited, to make the output easy to grep.
 | |
| #:
 | |
| #:    Passing `--only=`<method> will run only the methods named `audit_<method>`,
 | |
| #:    while `--except=`<method> will skip the methods named `audit_<method>`.
 | |
| #:    For either option <method> should be a comma-separated list.
 | |
| #:
 | |
| #:    Passing `--only-cops=`<cops> will check for violations of only the listed
 | |
| #:    RuboCop <cops>, while `--except-cops=`<cops> will skip checking the listed
 | |
| #:    <cops>. For either option <cops> should be a comma-separated list of cop names.
 | |
| #:
 | |
| #:    `audit` exits with a non-zero status if any errors are found. This is useful,
 | |
| #:    for instance, for implementing pre-commit hooks.
 | |
| 
 | |
| # Undocumented options:
 | |
| #     `-D` activates debugging and profiling of the audit methods (not the same as `--debug`)
