I've noticed that some of the latest upstream commits broke S.A.R.A. And now it doesn't compile. The fix is trivial (just some reordering in a function arguments' list) so I prefer to not flood the lists with a v4 with just for 2 lines change. For review and comments the code posted here is still valid. For those who want to compile S.A.R.A. with the latest upstream changes there is an always up-to-date patch available here: https://github.com/smeso/sara/compare/master...sarav3.patch I'm sorry for the inconvenient.
