// 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
