KindleGen binaries are no longer available for download

[slonopotamus]

1. https://www.amazon.com/gp/feature.html?docId=1000765211 says "KindleGen is no longer available for download."
2. All old download links from http://kindlegen.s3.amazonaws.com now give access denied

Downstream issue: asciidoctor/asciidoctor-epub3#363

Seems like there is nothing that can be done within kindlegen gem because KindleGen EULA doesn't allow redistribution.

Can confirm, I'm running into this too when using Travis CI or a local install.

OMG...

The even worse news is that Kindle Previewer doesn't have a Linux binary.

If you've already installed the kindlegem gem, you can salvage the kindlegen tar.gz file from under the ext directory of the extracted gem file. You can use that to make the kindlegen gem rebuildable, but that's as far as you can go.

I don't think this issue will be somehow fixed. kindlegen gem is just a thin wrapper to download KindleGen binary. But now there is nothing to download (without EULA violation).

There are higher chances that something will be done in asciidoctor/asciidoctor-epub3#363. asciidoctor-epub3 can use alternative ways to produce Mobi, not only through Kindlegen.

I have a workaround to make it work: #43. Digged to find the missing files and added them to the repo. Now, it works again! 🎉

Whereas Amazon is no longer releasing kindlegen, you can apparently snag an up-to-date binary from Kindle Previewer 3 at inside /Applications/Kindle Previewer 3.app/Contents/lib/fc/bin.

Not that I'd advocate going that way.

@tdtds while technically you gave me permissions to push commits to this repo, I would like you to look at #44. If you agree this is an acceptable way to go, let's merge it and push a new kindlegen gem release.
