for those of you who find the usefulness of /dev/screen questionable
and would like to see (in the good ol' unix tradition) a
special-purpose tool whose only job is to take a screenshot and write
it do stdout, i present the 'screenshot' utility attached.  note, to
be compliant with various lunixes you may need to copy it as
'snapshot', 'screengrab', 'grabscreen', 'screendump', 'snap' and 'xv
-grab -root -quit' so there will be no confusion among those used to
different unix variants.

i'll start working on the gui as soon as i'm done adding the -v option.

cheers, andrey

to compile:

	% 8c -FVw screenshot.c
	% 8l screenshot.8

to use:

	% 8.out | page

here's the man page:

     SCREENSHOT(1)                                                     SCREENSHOT(1)

     NAME
          screenshot - take a snapshot of the current display.

     SYNOPSIS
          screenshot

     DESCRIPTION
	Screenshot takes a snap of the current display and writes it
	as an image(6) format to standard output.

     SEE ALSO
          graphics(2),rio(1)

     BUGS
 	 Lacks a '-v' option.

	If the display is updated while the image is being written out
	the machine crashes and requires several reboots.
