Oh yes.. the problem is that I don't have much time to 
translate all existing comments. All new comments are in 
english ; but I suppose I'll have to do some hard work one 
day :)

Well ; the project is not so complex to compile - but there 
are several points that can be hard : you have to install 
full ipv6 support and development files, plus zlib 
developpment files, ssl includes.. this is not a totally 
obvious work ; except on platforms such as Linux (on Debian 
the installing is quite simple: all librairies and 
developpment packages are ready to install)
