-# (*) package-RPMBUILD: If not rpmbuild - mostly used for sudo'ing rpmbuild
-# (*) package-BUILD-FROM-SRPM: set this to any non-empty value, if your package is able to produce
-# a source rpms by running 'make srpm'
+# this is passed to rpmbuild, as well as to spec2make for "exporting" various rpm variable
+# to make; beware that some features, like --with=debug or --define 'foo bar' are not
+# well handled by spec2make as of this writing, which can cause issues.
+# hopefully this will be fixed...
+# (*) package-BUILD-FROM-SRPM: set this to any non-empty value,
