Matthias Stevens updated COMPRESS-263:
--------------------------------------

    Description: 
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.
