-Use this module to convert a username/groupname to a uid/gid number.
-
-Usage:
-
-```
-npm install uid-number
-```
-
-Then, in your node program:
-
-```javascript
-var uidNumber = require("uid-number")
-uidNumber("isaacs", function (er, uid, gid) {
-  // gid is null because we didn't ask for a group name
-  // uid === 24561 because that's my number.
-})
-```
