graceful-fs functions as a drop-in replacement for the fs module,
making various improvements.
The improvements are meant to normalize behavior across different
platforms and environments, and to make filesystem access more
resilient to errors.
## Improvements over [fs module](http://api.nodejs.org/fs.html)
* Queues up `open` and `readdir` calls, and retries them once
something closes if there is an EMFILE error from too many file
* fixes `lchmod` for Node versions prior to 0.6.2.
* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
`lchown` if the user isn't root.
* makes `lchmod` and `lchown` become noops, if not available.
* retries reading a file if `read` results in EAGAIN error.
On Windows, it retries renaming a file for up to one second if `EACCESS`
or `EPERM` error occurs, likely because antivirus software has locked
// use just like fs
var fs = require('graceful-fs')
// now go and do stuff with it...
