-# inflight
-
-Add callbacks to requests in flight to avoid async duplication
-
-## USAGE
-
-```javascript
-var inflight = require('inflight')
-
-// some request that does some stuff
-function req(key, callback) {
-  // key is any random string.  like a url or filename or whatever.
-  //
-  // will return either a falsey value, indicating that the
-  // request for this key is already in flight, or a new callback
-  // which when called will call all callbacks passed to inflightk
-  // with the same key
-  callback = inflight(key, callback)
-
-  // If we got a falsey value back, then there's already a req going
-  if (!callback) return
-
-  // this is where you'd fetch the url or whatever
-  // callback is also once()-ified, so it can safely be assigned
-  // to multiple events etc.  First call wins.
-  setTimeout(function() {
-    callback(null, key)
-  }, 100)
-}
-
-// only assigns a single setTimeout
-// when it dings, all cbs get called
-req('foo', cb1)
-req('foo', cb2)
-req('foo', cb3)
-req('foo', cb4)
