+# dezalgo
+
+Contain async insanity so that the dark pony lord doesn't eat souls
+
+See [this blog
+post](http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony).
+
+## USAGE
+
+Pass a callback to `dezalgo` and it will ensure that it is *always*
+called in a future tick, and never in this tick.
+
+```javascript
+var dz = require('dezalgo')
+
+var cache = {}
+function maybeSync(arg, cb) {
+  cb = dz(cb)
+
+  // this will actually defer to nextTick
+  if (cache[arg]) cb(null, cache[arg])
+
+  fs.readFile(arg, function (er, data) {
+    // since this is *already* defered, it will call immediately
+    if (er) cb(er)
+    cb(null, cache[arg] = data)
+  })
+}
+```
