-The final value of the web100 variables with some analysis details are  
stored in the web100srv.log file. The list of logged variables with a short  
description can be found in the [NDTProtocol#Appendix_A._web100_variables  
NDT Protocol document].
+The NDT always writes a one-line summary of the test to the web100srv.log  
file. This one-line summary contains the final values of some of the web100  
variables with an additional analysis details.
+
+The particular values are separated with commas without any spaces. The  
results are stored with the following order:
