-help could take a keyword argument. As a related matter, we should add
-info_include, because I think it's common that you know what you are
looking for than that you can enumerate everything you're not looking for.

I use | grep -A2 ts_type and have

export 'GREP_OPTIONS=--binary-files=without-match --directories=skip
--color=auto'

so that the relevant bits are hilighted, thus making scanning faster.
