+Simulation results are automatically saved to `test/data`.  If `sim.SAVE_RAW_DATA = true`, in addition to the output data, full time traces will be saved to `test/data/raw`.  (Caution: this option both slows down the simulations and requires considerable storage space to store the results.)

+Augur.jl includes plotters written for PyPlot and Gadfly.  To generate plots, just specify `pyplot` or `gadfly` when you run the simulations:

+Unit tests are included with Augur.jl, and can be run from the `test/runtests.jl` script:
