The FvwmInitBanner displays an Fvwm Logo in the center of the screen for 3 seconds. Fvwm will search directory specified in the ModulePath configuration option to attempt to locate FvwmBanner. Although nothing keeps you from launching FvwmBanner at start-up time, you probably don't want to. You can also give it an optional file parameter, like 'FvwmBanner doomface.xpm' or spcify an alternate default pixmap via configuration options.
FvwmBannerPixmap file Tells the module to display file instead of the built in pixmap.
Tells the module to display for sec seconds instead of default of 3.
