exptool is primarily collection of analysis methods used to analyze n-body simulations, primarily those running with EXP, though any n-body code could use the methodology (Generation 1).
As of 2018, exptool has expanded to be an all-purpose dynamical framework for studying disc galaxies (Generation 2).
As of 2020, exptool includes support for analysing stellar halos (Generation 3).
The tests/ directory contains simulation outputs to play with, as well as some usage examples for methods.
