-// Package binary implements translation between numbers and byte sequences
-// and encoding and decoding of varints.
-//
-// Numbers are translated by reading and writing fixed-size values.
-// A fixed-size value is either a fixed-size arithmetic
-// type (int8, uint8, int16, float32, complex64, ...)
-// or an array or struct containing only fixed-size values.
-//
-// Varints are a method of encoding integers using one or more bytes;
-// numbers with smaller absolute value take a smaller number of bytes.
-// For a specification, see http://code.google.com/apis/protocolbuffers/docs/encoding.html.
