### Set up debugging output ============================================

# Relative to this script unless it starts with a slash. This is because
# cwd is usually not $DIR when testing.

### Process args =======================================================

### Helpers ============================================================
# Append a string to $debug in UTF-8 rather than the default UTF-16

}
