How to use the stylus/lib/utils.find function in stylus

var stylusFile = function(context, path) {
    // Stylus adds .styl to paths for normal "paths" lookup if it isn't there.
    if (!/.styl$/.test(path)) {
      path += '.styl';
    }

    var paths = options.paths.concat(context);
    var found = utils.find(path, paths, options.filename)
    if (found) {
      return normalizePaths(found);
    }
  };

return imported
  }

  // Literal
  if (/\.css(?:"|$)/.test(path)) {
    literal = true
    if (!imported.once && !this.includeCSS) {
      return imported
    }
  }

  // support optional .styl
  if (!literal && !/\.styl$/i.test(path)) path += ".styl"

  // Lookup
  found = utils.find(path, this.paths, this.filename)
  if (!found) {
    found = utils.lookupIndex(name, this.paths, this.filename)
  }
