EDuke32 Parameters

Usage: eduke32 [files] [options]
Example: eduke32 nukeland.map -usecwd -cfg myconfig.cfg

Files can be of types {grp | zip | pk3 | pk4 | map | con | def | rts}.

Specifying a {grp|zip|pk3|pk4} file is equivalent to using the -g parameter.
If a .map file is specified, it is immediately loaded and launched as a usermap (equivalent to -map).
If a .con file is specified, it replaces GAME.CON (equivalent to -x).
If a .def file is specified, it is used as the main DEF file (equivalent to -h).
If a .rts file is specified, it is used as the main RTS soundbank (equivalent to -rts).
