+# 1. start pcscd in debug mode to generate a trace
+# pcscd --foreground --debug
+# 2. copy the trace into a file using Copy/Paste of your terminal
+# 3. Make sure the first line of the log file is the first output line
+# 00000000 debuglog.c:277:DebugLogSetLevel() debug level=debug
+# 4. run the script
+# ./pcscd_perfs.py log
+
+# Log file:
+# 00000000 debuglog.c:277:DebugLogSetLevel() debug level=debug
