# swy: reminder; these things get built with '$ spectool -g -R openbrf.spec'    to download the sources
#                                   and then '$ rpmbuild -ba openbrf.spec -vvv' to actually generate the source package and finally the binary package.
#      pretty funky compared to a PKGBUILD, not gonna lie. and the documentation is terrible. either too basic or too scattered all over the place.

# swy: autogenerate the version from the current date and time, assuming the build gets kicked from a callback,
#      use a global to grab the time only once, otherwise rpmbuild would call date various times and
#      sometimes copr will fail because it generates multiple source package files, go figure
