  "readme": "# once\n\nOnly call a function once.\n\n## usage\n\n```javascript\nvar once = require('once')\n\nfunction load (file, cb) {\n  cb = once(cb)\n  loader.load('file')\n  loader.once('load', cb)\n  loader.once('error', cb)\n}\n```\n\nOr add to the Function.prototype in a responsible way:\n\n```javascript\n// only has to be done once\nrequire('once').proto()\n\nfunction load (file, cb) {\n  cb = cb.once()\n  loader.load('file')\n  loader.once('load', cb)\n  loader.once('error', cb)\n}\n```\n\nIronically, the prototype feature makes this module twice as\ncomplicated as necessary.\n\nTo check whether you function has been called, use `fn.called`. Once the\nfunction is called for the first time the return value of the original\nfunction is saved in `fn.value` and subsequent calls will continue to\nreturn this value.\n\n```javascript\nvar once = require('once')\n\nfunction load (cb) {\n  cb = once(cb)\n  var stream = createStream()\n  stream.once('data', cb)\n  stream.once('end', function () {\n    if (!cb.called) cb(new Error('not found'))\n  })\n}\n```\n",
