// Baucis examples using Backbone
// ==============================

(function () {

  // A utility function for easily making requests to a Baucis API.  Supply Baucis
  // options such as `select` or `populate` in the first parameter, and regular
  // Backbone fetch options as the second parameter.
  function baucisFetch (options, fetchOptions) {
    fetchOptions = _.clone(fetchOptions || {});

        else fetchOptions.data[key] = value;
      });
    }

  // Fetch red vegetables, setting a few options
