Mirrored manufacturer datasheets.

This folder is empty until you run:

    php tools/fetch_docs.php

Until then the application links directly to each manufacturer's website, so
everything works — mirroring simply makes the links survive the manufacturer
reorganising their site or publishing a new revision.

The files are published by FAUDI Aviation / Sefiso and Parker Hannifin and
remain their copyright. Mirroring them for internal reference is routine; if
this application is going to be reachable by the public, check with whoever
handles that before serving the PDFs from your own domain. Deleting the files
in this folder reverts every link to the manufacturer's own site.
