 * This file is used in Dr. McKay's plugins for Updater integration
 * For more info on Dr. McKay's plugins, see http://www.doctormckay.com
 * For more info on Updater, see https://forums.alliedmods.net/showthread.php?t=169095
 * You may copy and use this file, but please be sure to change the URL to your own!
 * This file does the following tasks:
 * 		- Adds the plugin to Updater's updating pool (using UPDATER_BASE_URL/UPDATE_FILE (UPDATE_FILE should be defined prior to including this file))
 * 		- Creates a cvar CONVAR_PREFIX_auto_update to control whether Updater is enabled (CONVAR_PREFIX should be defined prior to including this file)
 * 		- Creates a version cvar CONVAR_PREFIX_version (CONVAR_PREFIX should be defined prior to including this file)
 * 		- Dynamically adds "A" to the version cvar based on whether Updater is installed and working
 * If you need to put code into OnAllPluginsLoaded, define ALL_PLUGINS_LOADED_FUNC with a function (doesn't need to be public) to be called inside of OnAllPluginsLoaded
 * 		For example, #define ALL_PLUGINS_LOADED_FUNC AllPluginsLoaded
 * 		AllPluginsLoaded() { ... }
 * If you need to put code into OnLibraryAdded, define LIBRARY_ADDED_FUNC with a function (doesn't need to be public) to be called inside of OnLibraryAdded
 * 		For example, #define LIBRARY_ADDED_FUNC LibraryAdded
 * 		LibraryAdded(const String:name[]) { ... }
 * If you need to put code into OnLibraryRemoved, define LIBRARY_REMOVED_FUNC with a function (doesn't need to be public) to be called inside of OnLibraryRemoved
 * 		For example, #define LIBRARY_REMOVED_FUNC LibraryRemoved
 * 		LibraryRemoved(const String:name[]) { ... }
 * Define RELOAD_ON_UPDATE and the plugin will reload itself upon being updated
