Blessings lifts several of curses' limiting assumptions, and it makes your code
pretty, too:

- Use styles, color, and maybe a little positioning without necessarily
  clearing the whole screen first.

- Leave more than one screenful of scrollback in the buffer after your program
  exits, like a well-behaved command-line app should.

- Get rid of all those noisy, C-like calls to tigetstr and tparm, so your code
  doesn't get crowded out by terminal bookkeeping.

- Act intelligently when somebody redirects your output to a file, omitting the
  terminal control codes the user doesn't want to see (optional).
