-// The GZipHeader class allows you to parse a gzip header, such as you |
-// 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. |
