        Open a directory (content, layouts, etc.) within the plugin origin. \n
        First run bridgetown plugins list to view source manifests currently
        set up on your site.\n
        Then look for the origin of the manifest and the folder you'd like to
        open.\n
        So for example, with an origin of SamplePlugin and a folder of
        Layouts, you'd run:\n
        bridgetown plugins cd SamplePlugin/Layouts
      DOC
      desc "cd <origin/dir>", "Open folder (content, layouts, etc.) within the plugin origin"

      # This is super useful if you want to copy files out of plugins to override.
      #
      # Example:
      #   bridgetown plugins cd AwesomePlugin/layouts
      #   cp -r * $BRIDGETOWN_SITE/src/_layouts
      #
      # Now all the plugin's layouts will be in the site repo directly.
