Usage: #{File.basename($0)} [OPTION] [FILE]

If FILE is skipped, this scripts waits for input from STDIN. Otherwise
FILE is opened, read, and used as input for the prettifier.

OPTION can be
  -s     to output the shortest possible JSON (precludes -l)
  -l     to output a longer, better formatted JSON (precludes -s)
  -i EXT prettifies FILE in place, saving a backup to FILE.EXT
  -h     this help
