positive.code: 
  Homebrew, like `git`(1), supports external commands. These are executable
  scripts that reside somewhere in the `PATH`, named `brew-`<cmdname> or
  `brew-`<cmdname>`.rb`, which can be invoked like `brew` <cmdname>. This allows you
  to create your own commands without modifying Homebrew's internals.
  
  Instructions for creating your own commands can be found in the docs:
  <https://docs.brew.sh/External-Commands>
  
negative.code: 
  ### `search` (<text>|`/`<text>`/`):
  
  Perform a substring search of cask tokens and formula names for <text>. If
  <text> is flanked by slashes, it is interpreted as a regular expression.
  The search for <text> is extended online to `homebrew/core` and `homebrew/cask`.
  If no search term is provided, all locally available formulae are listed.
