EDIT: okay, I'm the idiot for not actually opening the source archive and verifying that there's anything in there worth looking at.

You aren't the idiot in this equation. Inexplicably, the source can be found in zip or tar format on the download page:

https://github.com/Impedimenta/Suitcase/releases/tag/1.0.0-a...

The "source code" zip has the same files as in the repo. No source.

Holy hell, the source archive is huge.

I just saw how that the demo is slow to boot and wanted to see the horror of the code.

Ok no, there is no code in the archive. Only images.

I guess it isn't open source ¯\_(ツ)_/¯ Strange how GitHub has apparently become the default distribution platform

Yes, you're an idiot for thinking a project on GitHub is open source.

What a lame use of GitHub. Can I get the minute back I wasted reading that readme?
