Describe the bug
Trying to create a recipe for BBEdit by dropping the app on RR fails with the following

    latest_info = max(sparkle_info, key=lambda x: APLooseVersion(x[key]))
ValueError: max() arg is an empty sequence

To Reproduce
Steps to reproduce the behavior:

1. Dropping BBEdit.app on RR's Gui area
2. See error above

Expected behavior
RR should create the individual recipe parts

Desktop (please complete the following information):

• macOS: 10.13.6
• Recipe Robot Version: 2.2.0
• autopkg version: 2.4.1
• /usr/local/autopkg/python --version: 3.7.5

A good catch — BareBones doesn't actually use Sparkle for their update check XML. I might adjust Recipe Robot to accommodate their format.

However, I'd suggest that most BareBones apps already have recipes in the AutoPkg org on GitHub. BBEdit, for example. Still, good for RR to know what to do in case a new app is released.

Thank you.

I am aware that a recipe for BBedit already exists. However, it fails to download anything.
(I had reported an issue about this and just checked, only to see that you had replied. This somehow escaped my notice; I am sorry about that.)

This is the reason I was trying to create a separate recipe for it with RR.

RR 2.3.0 now contains special handling for Bare Bones appcast feeds. However I'm getting a ditto: Couldn't read PKZip signature error when running the generated download recipes in AutoPkg 3.0rc2. I'll look more into this.
