var CONFIG_USAGE = `

  ${clr('Configuration', 'bold')}


  Bankai is built on top of compilers for scripts, styles and documents.
  Each of them can be configured by adding a field to your project's
  package.json file.

  These three fields are, respectively: ${clr('"browserify"', 'cyan')}, ${clr('"sheetify"', 'cyan')} and
  ${clr('"documentify"', 'cyan')}. Each one should have a configuration object as it's value.

  There is currently one possible configuration field: "transform".

  It can be one of either:

  1. An array of transform names.
       ie:  ${clr('[ "vueify" ]', 'cyan')}
  2. An array of tuples transform name + configuration object.
       ie: ${clr('[[ "vueify", { "sass": { "includePaths": [ "src/assets/css" ] } } ]]', 'cyan')}


  Full example:

  ${clr(`{
    "browserify": {
      "transform": [
        [ "vueify", { "sass": { "includePaths": [ "src/assets/css" ] } } ]
      ]
    },
    "sheetify": {
      "transform": [
        "sheetify-cssnext"
      ]
    },
    "documentify": {
      "transform": [
        [ "posthtmlify", { "use": [ "posthtml-custom-elements" ] } ]
      ]
    }
  }`, 'cyan')}
