 Usage:
 
-  netmon [-t <check_interval>] [-n <max_failure>] [-l <log_file>] [-c <cmd>] [-p <ping_host>] [-d]
+  netmon [-t <check_interval>] [-n <max_failure>] [-l <log_file>]
+         [-c <cmd>] [-p <ping_host>] [-d]
   
   -t <check_interval>  specify how many seconds to wait between two checks
-  -n <max_failure>     specify how many continous network failures we get until we reboot the system
+  -n <max_failure>     specify how many continuous network failures we get
+                       before we reboot the system
   -l <log_file>        specify the log file
-  -c <cmd>             the command line to be executed when network failure is detected
+  -c <cmd>             the command line to be executed when
+                       network failure is detected
   -p <ping_host>       test the network by pinging given host
   -d                   run as a daemon process
 
 
 Debugging:
 
-  Declare macro `DEBUG` to enable debug level logging. This is enabled in CMake task by default.
