It's an external command for Homebrew that provides caveat descriptions for Homebrew formulae and casks.
This repository is an active fork of the original rafaelgarrido/homebrew-caveats, which is unmaintained. See rafaelgarrido/homebrew-caveats#10 for the rational behind this fork.
Most notably, this fork greatly simplifies the installation process for this subcommand.
Run the following command:
brew tap superatomic/caveats
To see caveats for a formula:
$ brew caveats redis
==> redis
To start redis now and restart at login:
brew services start redis
Or, if you don't want/need a background service you can just run:
/usr/local/opt/redis/bin/redis-server /usr/local/etc/redis.conf
This also works for casks:
$ brew caveats macfuse
==> macfuse
macfuse requires a kernel extension to work.
If the installation fails, retry after you enable it in:
System Settings → Privacy & Security
