Overview

This class is part of a private API. This class may only be used in the Homebrew/brew repository. Third parties should avoid using this class if possible, as it may be removed or changed without warning.

Class corresponding to the caveats stanza.

Each method should handle output, following the convention of at least one trailing blank line so that the user can distinguish separate caveats.

The return value of the last method in the block is also sent to the output by the caller, but that feature is only for the convenience of cask authors.
