  // Basic Plugin Logging Usage Instructions
  //
  // 1. Set this environment variable: NSPR_LOG_MODULES=<name>:<level>
  
  // Choose the <name> and <level> from this list (no quotes):
  
  // Log Names            <name>
  #define NPN_LOG_NAME    "PluginNPN"
  #define NPP_LOG_NAME    "PluginNPP"
  #define PLUGIN_LOG_NAME "Plugin"
  
  // Levels                <level>
  #define PLUGIN_LOG_ALWAYS 1
  #define PLUGIN_LOG_BASIC  3
  #define PLUGIN_LOG_NORMAL 5
  #define PLUGIN_LOG_NOISY  7
  #define PLUGIN_LOG_MAX    9
  
  // 2. You can combine logs and levels by separating them with a comma:
  //    My favorite Win32 Example: SET NSPR_LOG_MODULES=Plugin:5,PluginNPP:5,PluginNPN:5
  
  // 3. Instead of output going to the console, you can log to a file. Additionally, set the
  //    NSPR_LOG_FILE environment variable to point to the full path of a file.
  //    My favorite Win32 Example: SET NSPR_LOG_FILE=c:\temp\pluginLog.txt
  
  // 4. For complete information see the NSPR Reference: 
  //    http://www.mozilla.org/projects/nspr/reference/html/prlog.html
