-// might find at the beginning of a file compressed by gzip (ie, a .gz
-// file), or at the beginning of an HTTP response that uses a gzip
-// Content-Encoding. See RFC 1952 for the specification for the gzip
-// header.
-//
-// The model is that you call ReadMore() for each chunk of bytes
-// you've read from a file or socket.
