Query: REvolver: Automated running and matching of couplings and masses in QCD   In this article we present REvolver, a C++ library for renormalization group
evolution and automatic flavor matching of the QCD coupling and quark masses,
as well as precise conversion between various quark mass renormalization
schemes. The library systematically accounts for the renormalization group
evolution of low-scale short-distance masses which depend linearly on the
renormalization scale and sums logarithmic terms of high and low scales that
are missed by the common logarithmic renormalization scale evolution. The
library can also be accessed through Mathematica and Python interfaces and
provides renormalization group evolution for complex renormalization scales as
well.
