Editing OPTIONS

New to MBF, the OPTIONS lump allows wads to set game options, such as Doom Compatibility options, chat strings, and enemies options. 

The OPTIONS lump has the same format as eternity.cfg: A text file listing option names and values, optionally separated by blank or comment lines. Eternity.cfg indicates options which are allowed to be set in wads, with asterisks (*).

Wad authors are urged to use these options responsibly, because they should not be used to limit players, but to enhance the game. Many options such as automap colors are allowed to be set from wads, but they should only be done so if there are strong reasons to do so. More recommended to enforce are the compatibility (comp_) settings, because certain map effects (such as moving floor combinations) may depend on them to work properly.

==Options settable using the lump==
The Eternity.cfg file provides user-friendly explanation on each flag and if it's allowed to be set in wads. Here is an excerpt from the default Eternity.cfg, with only the wad-settable options. Note that the lines beginning with semicolons or brackets are treated as comments and do nothing.
