  This paper presents STrEAM (SuperTrace Evaluation Automated for Matching), a
Mathematica package that calculates all functional supertraces which arise when
matching a generic UV model onto a relativistic Effective Field Theory (EFT) at
one loop and to arbitrary order in the heavy mass expansion. STrEAM implements
the covariant derivative expansion to automate the most tedious step of the
streamlined functional matching prescription presented in arXiv:2011.02484 .
