--- Comment #3 from Robert-André Mauchin zebob.m@gmail.com --- I don't see any changes in %files.
I didn't mean you should add the macros to this package, you could create a separate package, like nim-packaging, for the macros. I don't know how nim package are built, but you could provide other macros in the future for %build, %install, %check and so on if they are standardized.
