help message mentions the formats that are unsupported #20
Description
--help shows that it's possible to output the result in the different formats but in fact only one is supported. I'd expect that it won't show unsupported configurations/options to not confuse me.
$ hoc --help
Usage (0.8): hoc [options]

-f, --format Output format (text|xml|json|int)
-e, --exclude Glob pattern to exclude files/dirs, e.g. "vendor/**"

$ hoc -f text
