+ help
+ Shows splash image and progress bar on framebuffer device.
+ Can be used during boot phase of an embedded device. ~2kb.
+ Usage:
+ - use kernel option 'vga=xxx' or otherwise enable fb device.
+ - put somewhere the fbsplash.ini file and image in .ppm format.
+ - $ setsid fbsplash [params] &
+ -c: hide cursor
+ -d /dev/fbN: framebuffer device (if not /dev/fb0)
+ -s path_of_image_file
+ -i path_of_ini_file
+ -f path_of_fifo (can be "-" for stdin)
+ - if you want to run applet only in presence of kernel parameter:
+ grep -q "fbsplash=on" </proc/cmdline && setsid fbsplash [params] &
+ - commands for fifo:
+ "NN" (ASCII decimal number) - percentage to show on progress bar
+ "exit" (or just close fifo) - well you guessed it
