+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.
+})
+```
