Glad to know meson is getting attention recently with the adoption by systemd and Xserver. I looked at the FAQ and found this technical mistake which most programmer won't be aware of:
Then the rest of physical elementary particles were examined and Meson was found to be available.
Formerly being a physics student, I find the sentence strange once I read it, and then noticed the problem.
Meson is a hadron, more specifically, hadrons that consists of a quark and a anti-quark. So, it is a composite particle rather than elementary one. For those still confused, quarks is elementary because it is not composed of other things. But meson is composed of quarks.
The real intent of this PR is to let the developers and users of meson to get interested in meson, physically, by googling it, rather than challenging the author. 😛
