## Helper script to show notes with chapters tagged for review.
## Notes must be written in markdown, then any chapters will be used
## as "review tip", while it's content will be the response.
## This script shows for each review tip the filename and last review time (file last modification date).
## To improve, add a review status mark at the end of the title (+/k:good review, -/x:bad review).
## e.g.
##      # Chapter to review xxkk (or --++)
##
