-The pool package exposes a `Pool` class which makes it easy to manage a limited
-pool of resources.
-
-The easiest way to use a pool is by calling `withResource`. This runs a callback
-and returns its result, but only once there aren't too many other callbacks
-currently running.
-
-```dart
-// Create a Pool that will only allocate 10 resources at once. After 30 seconds
-// of inactivity with all resources checked out, the pool will throw an error.
-final pool = new Pool(10, timeout: new Duration(seconds: 30));
-
-Future<String> readFile(String path) {
-  // Since the call to [File.readAsString] is within [withResource], no more
-  // than ten files will be open at once.
-  return pool.withResource(() => return new File(path).readAsString());
-}
-```
-
-For more fine-grained control, the user can also explicitly request generic
-`PoolResource` objects that can later be released back into the pool. This is
-what `withResource` does under the covers: requests a resource, then releases it
-once the callback completes.
-
-`Pool` ensures that only a limited number of resources are allocated at once.
-It's the caller's responsibility to ensure that the corresponding physical
-resource is only consumed when a `PoolResource` is allocated.
-
-```dart
-class PooledFile implements RandomAccessFile {
-  final RandomAccessFile _file;
-  final PoolResource _resource;
-
-  static Future<PooledFile> open(String path) {
-    return pool.request().then((resource) {
-      return new File(path).open().then((file) {
-        return new PooledFile._(file, resource);
-      });
-    });
-  }
-
-  PooledFile(this._file, this._resource);
-
-  // ...
-
-  Future<RandomAccessFile> close() {
-    return _file.close.then((_) {
-      _resource.release();
-      return this;
-    });
-  }
-}
