-// This file offers functions to determine the type of binary input source. The
-// type recognition here is not 100% accurate, it only offers a quick and rough
-// check about the input source. The general functions use RangeCheckedBytePtr
-// as input, there are also linux only functions that use StringPiece as input.
-// A linux only IsRawLite() method is also implemented.
-// The "lite" implementation focuses on performance and guarantees to not read
-// more than specified by GetNumberOfBytesForIsRawLite.
