+# promise-call-limit
+
+Call an array of promise-returning functions, restricting concurrency to a
+specified limit.
+
+## USAGE
+
+```js
+const promiseCallLimit = require('promise-call-limit')
+const things = getLongListOfThingsToFrobulate()
+
+// frobulate no more than 4 things in parallel
+promiseCallLimit(things.map(thing => () => frobulateThing(thing)), 4)
+  .then(results => console.log('frobulated 4 at a time', results))
+```
+
+## API
+
+### promiseCallLimit(queue Array<() => Promise>, limit = defaultLimit)
+
+The default limit is the number of CPUs on the system - 1, or 1.
+
+The reason for subtracting one is that presumably the main thread is taking
+up a CPU as well, so let's not be greedy.
+
+Note that the array should be a list of Promise-_returning_ functions, not
+Promises themselves.  If you have a bunch of Promises already, you're best
+off just calling `Promise.all()`.
+
+The functions in the queue are called without any arguments.
