Grab a feed and make a Kindle book out of it's latest entry

This script downloads an RSS feed, assembles it's latest entry into a nice HTML file, downloads all of the assets required, generates a Kindle .mobi book with Amazon's official tool, sends me a Pushbullet notification that it worked, and uploads the .mobi book to my Dropbox.

If you wanted, you could then have a tool like this upload it to your Kindle wirelessly.

Set-up:

Copy parse.sh and dropbox_uploader.sh to your working directory that you'd like the script to live
chmod +x parsh.sh dropbox_uploader.sh

./ubuntu-image.sh --developer-mode pc
