(synopsis "Take a screenshot of the contents of the Linux framebuffer")
(description
"fbcat saves the contents of the Linux framebuffer (@file{/dev/fb*}), or
a dump therof. It supports a wide range of drivers and pixel formats.
@command{fbcat} can take screenshots of virtually any application that can be
made to write its output to the framebuffer, including (but not limited to)
text-mode or graphical applications that don't use a display server.
Also included is @command{fbgrab}, a wrapper around @command{fbcat} that
emulates the behaviour of Gunnar Monell's older fbgrab utility.")
