Ideas for managing game manuals

[ecto]

I just had an idea when I was installing several ScummVM and dosbox games from my gog account:
GOG has a lot of additional manuals / maps and reference cards for all the games. Since many of those old games (especially those Sierra adventures) rely on those manuals for the copy protection, it would be great to implement them into retropie.

I was thinking of a tiny web server, where you can download or view the manuals for the currently running game. Maybe if there is a specific folder in the game directory (like '''scummvm/space quest 1/manual''') it just lists those files for viewing on the phone etc.

Problem is: I don't know where to start, as I'm a *nix illiterate... Maybe if someone has a starting point for me so I could wriggle through this project from there?

Thanks!
