Since Haskell is usually nice to parse, wouldn't it be
interesting to replace a pretty printer program for layout
manuals? I saw in your first link that the teacher provided
a tool to check for non-compliant layout, but wouldn't it
be easier to provide a pretty-printer (with line size as one
parameter to the command line)?

(By the way, I once saw in a latex tutorial that some research
found that 66 letters was a good standard for running text
readability. I was never able to find such research, it wasn't
properly quoted in that tutorial, but I adopted 66 as a parameter
to 'fmt' when writing messages and Haskell code.)

Best,
