      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.
