In fact, it's +barely even readable. + +As with `util.inspect` and `JSON.stringify`, larger objects will +produce larger signature strings. + +Because sigmund is a bit less strict than the more thorough +alternatives, the strings will be shorter, and also there is a +slightly higher chance for collisions. For example, these objects +have the same signature: + + var obj1 = {a:'b',c:/def/,g:['h','i',{j:'',k:'l'}]} + var obj2 = {a:'b',c:'/def/',g:['h','i','{jkl']} + +Like a good Freudian, sigmund is most effective when you already have +some understanding of what you're looking for. It can help you help +yourself, but you must be willing to do some work as well. + +Cycles are handled, and cyclical objects are silently omitted (though +the key is included in the signature output.) + +The second argument is the maximum depth, which defaults to 10, +because that is the maximum object traversal depth covered by most +insurance carriers. diff --git
