+/// \brief Define Name of Root Logger
+///
+/// In BIND-10, the name root logger of a program is the name of the program
+/// itself (in contrast to packages such as log4cplus where the root logger name
+//  is something like "root").  These trivial functions allow the setting and
+// getting of that name by the logger classes.

+/// \brief Set root logger name
+///
+/// This function should be called by the program's initialization code before
+/// any logging functions are called.
+///
+/// \param name Name of the root logger.  This should be the program name.
+void setRootLoggerName(const std::string& name);

+
+/// \brief Expand logger name
+///
+/// Given a logger name, returns the fully-expanded logger name.  If the name
+/// starts with the root logger name, it is returned as-is.  Otherwise it is
+/// prefixed with the root logger name.
+///
+/// \param name Name to expand.
+///
+/// \return Fully-expanded logger name.
