+% example_03.bc
+%
+% Very minimalistic demo. Writes a short message in graphics mode and lets you
+% boot linux or start from local disk.
+%
+% Notes:
+%  - the video mode number is no longer hardcoded and we exit if the video mode
+%    could not be set
+%
+%  - we use a background picture
+%
+% Test with (from top level dir [/usr/share/gfxboot]) 'gfxtest -t example_03'.

+% action
+%    0:         ok, stay in input loop
+%    1:         switch to text mode (that is, continue with the non-gfxboot bootloader interface)
+%  >=2:         boot
+%
+% Notes:
+%  - key = 0 indicates the bootloader timeout is up.
+%  - input_buffer is the command line that you would have normally entered in the bootloader.
+%  - menu_entry is only relevant for grub and is the 'title' section you want to boot. input_buffer
+%    is appended to the kernel options in this case.
