.Nm scummvm
.Op Ar OPTIONS
.Op Ar GAME
.Sh DESCRIPTION
.Nm
is an interpreter that will play numerous adventure and
role-playing games based on a variety of game engines.
.Pp
.Ar GAME
is a short name of game to load.
This can be either a built-in gameid (as given by
.Fl -list-games ) ,
or a user-configured target (as given by
.Fl -list-targets ) .
.Sh OPTIONS
The meaning of most long options (that is, those options starting with a
double-dash) can be inverted by prefixing them with
.Cm no- .
For example,
.Fl -no-aspect-ratio
will turn aspect ratio correction off.
This is useful if you want to override a setting in the configuration file.
