Sometimes it can be useful to record what's on your screen. For example, you can use screen shots for documentation. Also, providing a view of an error can help others to diagnose the problem. You can take a shot of the whole screen quite easily in a raw image format like this.

cat /dev/screen > /tmp/shot.pic # take screenshot
window page /tmp/shot.pic # see the file
sleep 10; cat /dev/screen > /tmp/shot.pic # with delay
cat /dev/screen | topng > /tmp/shot.png # small file
ls -l /tmp/shot.png /tmp/shot.pic # display pic as png


hget http://plan9.stanleylieber.com/src/rio.mono.tgz > $home/rio.mono.tgz
tar zxf rio.mono.tgz
cd rio.mono
mk install

To add this version of rio to open on launch.

An argument for simplicity and clarity.
