====Loading main game WADs====
Eternity looks for the main game WADs (IWADs), e.g. doom2.wad, at these locations:
* IWAD file paths in user/system.cfg;
* the -iwad command-line parameter;
* the [[Doom Wiki:Environment variables|'''DOOMWADDIR''' or '''DOOMWADPATH''' environment variables]];
* the IWAD in the working directory;
* the IWAD file under the appropriate game folder of the base directory, which can be found using the -game parameter.
