I present EOS, an open-source software dedicated to a variety of tasks in the
processing of flavor physics observables. EOS is written in C++ and offers both
a C++ and a Python interface. It is developed for three main tasks, the
production of theoretical predictions for flavor physics observables; the
inference of theoretical parameters from an extensible database of likelihoods;
and the production of Monte Carlo samples of flavor processes for sensitivity
studies.Comment: 9 pages, 4 figure
