 Interaction channel plug-ins specify properties of the interaction channel, like the neutrino species that undergo this interaction, and provide functions to calculate quantities like the differential cross section $\tdiffx{\sigma (E_\nu, E_e)}{E_e}$ or the kinematically allowed energy range.
 This modular design makes sntools easily extensible, with roughly 100 lines of code required to add a new input format or interaction channel.
 
-Finally, \texttt{genevts.py} collects the events generated in all interaction channels and writes them to a text file in the NUANCE format\footnote{See \url{http://neutrino.phy.duke.edu/nuance-format/} for a description of this format.}, which can be used as an input file for a full detector simulation.
