A .zip file is actually a collection of zlib compressed files, so you cannot use zlib_decompressor directly on the
zip file, but you have to extract the files within the zip file first, then decompress them. But how to do that, I
don't know (in boost context). But there are plenty of zip archive libs around, f.i. 
http://www.artpol-software.com/ZipArchive/Default.aspx . I wouldn't be surprised though if there is a boost way of
doing this...
