   2 # A quick and dirty script to take a screenshot, upload it via scp
   3 # and put a link to it in the clipboard for easy pasting to i.e. IRC.
   4 # It assumes a lot of things, e.g. that ssh to the target host has
   5 # been set up with a working private key, and that xclip and
   6 # gnome-screenshot is installed.

   8 # If all you have is a hammer, everything looks like a nail.
