# Usage: scripts/coverage.sh [out folder, default .pio/coverage]
# Out: summary.json (gcovr), coverage.svg (the README's badge), index.html (line by line).
# What it measures: the lines of lib/ that compile on a PC. Not lib/SD (the card's driver) and not
# src/ (the Apps, the Services, everything that needs the device): those have no host tests.
