Issue with the DIRECTORY.md script about nim HOT 4 CLOSED

I could not reproduce the issue on my desktop, I have to investigate this a little on my laptop.
Thank you for the PR, I will merge this tomorrow. Ping me if I forget.

The script assumes implementations conform to the regular Nim module format, with the description being Doc comments. I wanted to mention on your PR, but got distracted.

I propose we just add the requirement to the guidelines.

The script should fall back on the file name to get the title in case it can't be read from the first line. I'll check it a bit later.

I've checked and can't reproduce. All files are detected, including the scripts directory, which I'm adding to a list of ignored sub dirs in a follow-up PR.
