Usage: $0 [ARGUMENTS]

Invokes ./creativity-cli (and so is typically run from the build directory)
using a default set of parameter values derived from the median values of
simulations that produce semi-consistent writing.  Any added ARGUMENTS (other
than --help and --dry-run) are added to the end of the ./creativity-cli
argument list, override the default.

Output is placed in

    ./results/\$DATE~~\$HASH/\$TYPICAL/creativity-\$SEED.crstate.xz

where DATE and HASH are generated from the current git commit date and hash,
and TYPICAL defaults to "typical" if not externally set in the environment.

Example usage:

    TYPICAL=costly-piracy ./typical-sim.sh --piracy-cost 100

To see a list of the options that creativity-cli will be called with without
actually invoking it, add a --dry-run option.
