+# wrappy
+
+Callback wrapping utility
+
+## USAGE
+
+```javascript
+var wrappy = require("wrappy")
+
+// var wrapper = wrappy(wrapperFunction)
+
+// make sure a cb is called only once
+// See also: http://npm.im/once for this specific use case
+var once = wrappy(function (cb) {
+ var called = false
+ return function () {
+ if (called) return
+ called = true
+ return cb.apply(this, arguments)
+ }
+})
+
+function printBoo () {
+ console.log('boo')
+}
+// has some rando property
+printBoo.iAmBooPrinter = true
+
+var onlyPrintOnce = once(printBoo)
+
+onlyPrintOnce() // prints 'boo'
+onlyPrintOnce() // does nothing
+
+// random property is retained!
+assert.equal(onlyPrintOnce.iAmBooPrinter, true)
+```
