+Examples of usage:
+
+1. Use log directory and results directory with a specific date range:
+   python analyze_startup.py --log-dir ./logs --results-dir ./results --min-date 2023-07-01 --max-date 2023-12-31
+
+2. Use specific log files with automatic labels:
+   python analyze_startup.py -f ./logs/startup_lr62-prod-01.log -f ./logs/startup_lr62-prod-02.log
+
+3. Use specific log files with custom labels:
+   python analyze_startup.py -f ./logs/startup_lr62-prod-01.log -l prod01 -f ./logs/startup_lr62-prod-02.log -l prod02
+
+4. Combine log directory and specific files:
+   python analyze_startup.py --log-dir ./logs -f ./logs/startup_lr62-dev.log -l dev --results-dir ./results --min-date 2023-07-01
