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
