> GZIP is not a compression algorithm "as such". The de facto (and currently
> the only supported) compression algorithm it uses is DEFLATE. GZIP adds a
> header of minimum 10 bytes and a footer of 8 bytes the the "Deflated" data
> stream. Find out more here: http://en.wikipedia.org/wiki/Gzip#File_format
> I have no problem with the current GZIP support, but it would be nice if
> CommonsCompress would also have compression and decompression support for
> "raw" DEFLATE streams and DEFLATE streams with the zlib header.
> Similarly to the GZIP support in Commons Compress these functionality can be
> implemented very easily using the standard java.util.zip package, as done in
> the provided patch.
