First of all, thanks for the feedback

The point is to facilitate the use of all the formats which use Deflate 
such as ZIP, PNG, or PDF, for pure C++ projects and the Boost 
environment. As for current wrapped support, there is in 
Boost.Iostreams, but if I read the docs correctly it does not support 
raw Deflate (RFC1951) which is problematic for formats or protocols 
which rely on it directly, such as WebSockets' per-message Deflate, or 
decompressing compressed data from a Microsoft HTTP server (which are 
non-compliant and use RFC1951 instead of RFC1950). Furthermore, it 
doesn't allow much room for customization of the engine parameters (no 
predefined dictionary for example).
