// Map groups

// To use a mapgroup, it needs to be defined in a keyvalues
// block such as the example below, as well as listed in the
// 'mapgroupsMP' block within the game mode that will run it,
// such as the example above.
//
// Then launch the server with '+mapgroup MAPGROUPNAME'
//
// Example:
//
// srcds -game csgo +game_mode 1 +mapgroup mg_bomb_se +map de_nuke_se
