+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped

      The library also supports reading and writing files in gzip (.gz) format
   with an interface similar to that of stdio using the functions that start
   with "gz".  The gzip format is different from the zlib format.  gzip is a
   gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
 
+     This library can optionally read and write gzip streams in memory as well.
+
      The zlib format was designed to be compact and fast for use in memory
   and on communications channels.  The gzip format was designed for single-
   file compression on file systems, has a larger header than zlib to maintain
   directory information, and uses a different, slower check method than zlib.
 
-     This library does not provide any functions to write gzip files in memory.
-  However such functions could be easily written using zlib's deflate function,
-  the documentation in the gzip RFC, and the examples in gzio.c.
-
      The library does not install any signal handler. The decoder checks
   the consistency of the compressed data, so the library should never
   crash even in case of corrupted input.
