A simple and 'low-level' source code comments parser and gitHub flavored markdown API documentation generator.

var Promise,
  slice = [].slice;
Promise = require('yaku');
module.exports = function(fn, self) {
  return function() {
    var args;
    args = 1 <= arguments.length ? slice.call(arguments, 0) : [];
    if (typeof args[args.length - 1] === 'function') {
      return fn.apply(self, args);
    }
    return new Promise(function(resolve, reject) {
      args.push(function(err, rs) {
        if (err) {
          return reject(err);
        } else {
          return resolve(rs);
        }
      });
      return fn.apply(self, args);
    });
  };
};
