commit 231bfcdc0391cde9077e6ae0cd14dc6831fb1b88
from: Omar Polo <op@omarpolo.com>
date: Mon Dec 21 13:38:31 2020 UTC

make -d handle correctly non-absolute paths

before the -d option only accepted absolute paths, and this wasn't
documented.  Even more, with the default value of "docs" it won't
work.  Now it transforms all relative paths to absolute paths before
going on.
