I'm downloading PDF approach plates from Navigraph, and i have a folder per airport with files named after their corresponding approach / departure etc.

Now I'd like to take such a folder with a bunch of PDF files, automatically generate an index and combine them to a single .mobi file that i can send to my Kindle.

The index created can be very simple and consist of the file name (without the extension). Tapping an index item should jump to the correct page for that chart.

I know there is a host of apps that combine comic book jpg's to ebooks, but is there anything that does the above please?
