+    screenFetch is a "Bash Screenshot Information Tool". This handy Bash
+    script can be used to generate one of those nifty terminal theme
+    information + ASCII distribution logos you see in everyone's screenshots
+    nowadays. It will auto-detect your distribution and display an ASCII
+    version of that distribution's logo and some valuable information to the
+    right. There are options to specify no ascii art, colors, taking a
+    screenshot upon displaying info, and even customizing the screenshot
+    command! This script is very easy to add to and can easily be extended.
