```shell
$ brew typecheck homebrew/bundle
No sorbet/ directory found. Maybe you want to run 'srb init'?

A type checker for Ruby

Usage:
  srb                                 Same as "srb t"
  srb (init | initialize)             Initializes the `sorbet` directory
  srb rbi [options]                   Manage the `sorbet` directory
  srb (t | tc | typecheck) [options]  Typechecks the code

Options:
  -h, --help     View help for this subcommand.
  --version      Show version.
