#: * `gist-logs` [`--new-issue`|`-n`] <formula>:
#: Upload logs for a failed build of <formula> to a new Gist.
#:
#: <formula> is usually the name of the formula to install, but it can be specified
#: in several different ways. See [SPECIFYING FORMULAE](#specifying-formulae).
#:
#: If `--with-hostname` is passed, include the hostname in the Gist.
#:
#: If `--new-issue` is passed, automatically create a new issue in the appropriate
#: GitHub repository as well as creating the Gist.
#:
#: If no logs are found, an error message is presented.
