Ok. New macros:

# Disttag macros (you really only want to use %{disttag})
# When we get to Fedora Core 6, we'll need to revisit this.

%disttaglong %{expand:%%(rpm -qf --qf '%{VERSION}' /etc/redhat-release)}
%rheldisttag %{expand:%%(echo %{disttaglong} | sed -e 's/[^0-9.]//g' -e
's/^/el/')}
%rhldisttag  %{expand:%%(echo %{disttaglong} | cut -d "." -f 1 | sed -e
's/^/rh/')}
%fcdisttag   %{expand:%%(echo %{disttaglong} | sed -e 's/^/fc/')}
%disttag     %{expand:%%(if echo %{disttaglong} | grep "[^0-9.]"

  case "%{rheldisttag}" in \
    ( "el2" ) \
    echo 0.%{rheldisttag} \
    ;; \
    ( "el3" ) \
    echo 1.%{rheldisttag} \
    ;; \
    ( "el4" ) \
    echo 2.%{rheldisttag} \
    ;; \
    ( "el5" ) \
    echo 3.%{rheldisttag} \
    ;; \
  esac; \
else \
  case "%{disttaglong}" in \
    ( "7.0" | "7.1" | "7.2" | "7.3" | "8" | "9" ) \
    echo 0.%{rhldisttag} \
    ;; \
    ( "1" | "2" | "3" ) \
    echo 1.%{fcdisttag} \
    ;; \
    ("4" | "5" | "6" ) \
    echo 2.%{fcdisttag} \
    ;; \
  esac; \
fi;)}

Is anyone opposed to adopting the %{disttag} methodology as the
documented method for supporting single spec files for multiple Fedora
distros? If not, I'll start writing it up.
