Neat. What type of speedup or space savings are you seeing? I just recently played around with lrzip (Long Range Zip by Con Kolivas) and came away quite disappointed by it's speed. It would only give me around a 10-15% space savings over bzip2, but at a cost of having to use lots more memory and lots more CPU (multiple cores actually) to get anywhere close to the native bzip2 compression speed. Of course I was compressing already compressed files in one test, but in another test I was compressing pretty regular 5gb Magma Talus volvanos (EDA design tool file format) and just not seeing good results. I had also compiled in the LZO library and tried that, but bzip2 and even gzip were just as good if not much better. Sorry I don't have numbers handy. Now onto the patch commentary. Would it be possible to change the code to support more compression schemes, specifically the BZIP2 standard would be good to be able to implement. Your code is so nicely done, that it shouldn't be hard to do, except the #ifdefs are going to get ugly quickly as more are added.
