+// Package pool contains helpers for pooling structures distinguishable by
+// size.
+//
+// Quick example:
+//
+//   import "github.com/gobwas/pool"
+//
+//   func main() {
+//      // Reuse objects in logarithmic range from 0 to 64 (0,1,2,4,6,8,16,32,64).
+//      p := pool.New(0, 64)
+//
+//      buf, n := p.Get(10) // Returns buffer with 16 capacity.
+//      if buf == nil {
+//          buf = bytes.NewBuffer(make([]byte, n))
+//      }
+//      defer p.Put(buf, n)
+//
+//      // Work with buf.
+//   }
+//
+// There are non-generic implementations for pooling:
+// - pool/pbytes for []byte reuse;
+// - pool/pbufio for *bufio.Reader and *bufio.Writer reuse;
+//
