I think that is all for now. I have had to merge on the run as my patch was based on the old version with h/c glued together : )

It might be a good idea to allow these to be used without recompiling the program, but through a flag you can call it with from your shell.

I was looking for an explanation for the differences you've introduced, but Google didn't really turn anything relevant up, and the README doesn't really explain the differences either. I can see that you definitely put some thought into this, but the code is really cryptic and difficult to get a hold of without taking a while to step through a bunch of parts in my head. Are you able to explain what exactly is going on from a higher-level point of view, and the advantages and disadvantages of these new algorithms?

@CoolOppo, yeah sorry about the terse information.

• VLE. This change is not backwards compatible. VLE option is just moving from the fixed header of the patch 3x64bit [24 bytes] to something more variable in length, say between [3 and 30]. This is a personal choice and might not be everybody's taste, though. See more info at https://github.com/r-lyeh/vle
• SAIS. This change should remain backwards compatible. The SAIS option is to avoid a recursion crash as seen in Reported crashes with 4.3 #1. The patch seems to work but needs some more (real) testing, as my usage of bsdiff is quite limited.

I could have sent two PR instead, but got it difficult to do so, as my fork was pretty outdated and diverged too much from base. Sorry about that.

ping @mendsley

Has this been abandonned? if so, why?
