# read-installed

structure with all the data.
npm uses this.
## 2.0.0
Breaking changes in `2.0.0`:
The second argument is now an `Object` that contains the following keys:
* `depth` optional, defaults to Infinity
* `log` optional log Function
* `dev` optional, default false, set to true to include devDependencies
## Usage
```javascript
var readInstalled = require("read-installed")
// optional options
var options = { dev: false, log: fn, depth: 2 }
readInstalled(folder, options, function (er, data) {
...
})
```
