> 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.
