Some updates have been done to the spec, and I've been retrying to have the compilation on Copr.
I had some serious problem in having Copr hooked with the GitHub accounts,
so I spoke with a couple of hackers in IRC, and they suggested me to
directly upload the .srpm. Works like a charm. Not very automated
though.
I wonder if there's some better way to achieve this. But time is short, so I call it a day.
