# Plaintext-IO benchmark. Runs INSIDE the terminal under test as its shell
# (run_one.sh arranges that); $1 names the terminal for the result file.
#
# Methodology (moktavizen/terminal-benchmark): `time cat` an 11 MB text file,
# 5 runs. Timed with zsh's EPOCHREALTIME instead of `time` so the driver can
# collect results from a file instead of reading the screen.
