Hmm, that page mentions interpreter plugins in the [core package]
section without any example file name.

As Andrew mentioned already, the ex) stands for example.

Yes.

You might want to mention that to the people who maintain the download
site.  Check the output of

  rpm --query --info esci-interpreter-perfection-v330-0.2.0-1.x86_64.rpm
