abstract = {Studying the impact of new-physics models on
low-energy observables necessitates matching to effective
field theories at the relevant mass thresholds. We introduce
the first public version of Matchete, a computer tool for
matching weakly-coupled models at one-loop order. It uses
functional methods to directly compute all matching contributions
in a manifestly gauge-covariant manner, while simplification
methods eliminate redundant operators from the
output. We sketch the workings of the program and provide
examples of how to match simple Standard Model
extensions},
