+# sprintf() for node
+
+## Install
+
+    npm install sprintf
+
+## How to
+
+Works exactly like http://www.diveintojavascript.com/projects/javascript-sprintf, except that it exports those two functions:
+
+    sprintf = requrie('sprintf').sprintf;
+    vsprintf = require('sprintf').vsprintf;
+
+Have fun!
