404 not found - example files - pdf and epub

[neoneye]

I'm new to AsciiDoc and is checking out the example files.

On this page:
https://asciidoc-py.github.io/index.html

The following link:
PDF formatted AsciiDoc User Guide
refers to
https://asciidoc-py.github.io/asciidoc.pdf
However this is a 404.

Similar with the epub links, also 404.
