# Note, that for these examples we pass ask_overwrite=False and reset=True to the Simulation constructor. This will suppress
# prompts that ask the user if they want to overwrite existing files, which would would prevent these examples from running on their
# own when building the documentation pages. Alternatively, calling cratermaker.cleanup(simdir) will remove all pre-existing output files.
