A Configurable Status Line for HCat

Using what you’ve learned in this chapter, revisit the hcat application that you built earlier. Update hcat to support a configurable status bar that will show up at the bottom of the output. The status bar configuration should be stored on disk in a configuration file (for example ~/.config/hcat.conf). Allow users to specify which fields they want to see, what order they should appear in, and the maximum width of each field.
