  * Use the environment variable NS_LOG to define a ';'-separated list of
- * logging components to enable. For example, NS_LOG=a;b;c;DAFD;GH
- * would enable the components 'a', 'b', 'c', 'DAFD', and, 'GH'.
- * NS_LOG=* will enable all available log components.
+ * logging components to enable. For example (using bash syntax), 
+ * NS_LOG="OlsrAgent" would enable one component; 
+ * NS_LOG="OlsrAgent;Ipv4L3Protocol" would enable two
+ * components, etc.  NS_LOG="*" will enable all available log components.
+ * For each component, the "debug" log level is enabled by default.

+ * To obtain more components than just debug log level, more components

  * syntax: NS_LOG='Component1=func|param|warn;Component2=error|debug'
  * This example would enable the 'func', 'param', and 'warn' log
  * levels for 'Component1' and the 'error' and 'debug' log levels
