+About OpenBSD Port
+==================
+
+I've decided not to do OpenBSD port. Some preparations has been made both
+by myself and (mainly) by Justin Crawford, so finish it shouldn't be difficult.
+Personally, after installing OpenBSD and trying to finish the port I've
+discovered that g++ supplied by OpenBSD (version 5.7) doesn't support c++11.
+This means we lose the ability to use to_string() and stoi() functions. I could
+write replacements for them, or try to get c++11 working on OpenBSD. But I
+decided not to. At least for the moment.
+
+I don't know OpenBSD, it's unfamiliar ground for me. And while FreeBSD was easy
+to get into, I have found OpenBSD a little bit more difficult.
+
+So, no OpenBSD port for now. If you are OpenBSD user and know a little bit c++
+finishing the port should be easy (once you get C++11 working).
