Post-publication edit

[Paul Frields]

I had to make a post-publication edit to our most recent COPR article.
It wasn't clear before publication that one of the included repos
included material not eligible to redistribute. (Thus making it
ineligible also for COPR.)

I talked to the COPR folks as well as the author and took steps to
remove it from the article. I included an editors' note with an
apology for the issue. Thanks to the COPR folks as well for acting
swiftly. In the future, let's make sure that included repos are
appropriate.

By the way, COPR has a function where you can make a report if you
find material there that doesn't belong -- like software that is not
eligible to redistribute.
