Query: RunDec: a Mathematica package for running and decoupling of the strong
  coupling and quark masses   In this paper the formulae are collected which are needed for the computation
of the strong coupling constant and quark masses at different energy scales and
for different number of active flavours. All equations contain the
state-of-the-art QCD corrections up to three- and sometimes even four-loop
order. For the practical implementation {\tt Mathematica} is used and a package
containing useful procedures is provided.
