FOSS tool to do general stats from text indata

[Emanuel Berg <incal@dataswamp.org>]

Is there a CLI and FOSS tool that creates stats from text
indata - e.g.,

  $ txt2stats path/to/indata/*.txt

I mean a general tool, but with options to tweak the report
included, of course.

To produce neat stats, maybe even figures, and generate fun
facts of the kind

   The longest word that occurs more frequently than 0.01 ...

   The most common words to start a sentence ...

   Average paragraph length ...

   And even more crazy facts and stuff that you never think
   about until the stats tell you!

What do we have on that area?
