	Usage
	  $ replace-in-files <files…>

	Options
	  --regex           Regex pattern to find  (Can be set multiple times)
	  --string          String to find  (Can be set multiple times)
	  --replacement     Replacement string  (Required)
	  --ignore-case     Search case-insensitively
	  --no-glob         Disable globbing

	Examples
	  $ replace-in-files --string='horse' --regex='unicorn|rainbow' --replacement='🦄' foo.md
	  $ replace-in-files --regex='v\\d+\\.\\d+\\.\\d+' --replacement=v$npm_package_version foo.css
	  $ replace-in-files --string='blob' --replacement='blog' 'some/**/[gb]lob/*' '!some/glob/foo'

	You can use the same replacement patterns as with \`String#replace()\`, like \`$&\`.
