+== External scripts/programs with i3status
+
+In i3status, we don’t want to implement process management again. Therefore,
+there is no module to run arbitrary scripts or commands. Instead, you should
+use your shell, for example like this:
+
+*Example for prepending the i3status output*:
+--------------------------------------------------------------
+i3status | while [ 1 ]
+do
+       read line
+       echo "mystuff | $line"
+done | i3bar -d
