Ok, here goes:



[meetsma waters test]$ cat specfile 

%define cvsdate <date in past>




%changelog
* Thu May  7 2003
- manual rebuild
[meetsma waters test]$ gawk -v date="`date +'%a %b %e %Y'`" '{ if ($1=="%changelog") {print $1"\n* " date " me <me pc com>\n- autorebuild"; next} print }' specfile |sed "s/^%define cvsdate .*$/%define cvsdate `date -I`/" >specfile.new
[meetsma waters test]$ cat specfile.new 

%define cvsdate 2003-05-08




%changelog
* Thu May  8 2003 me <me pc com>
- autorebuild
* Thu May  7 2003
- manual rebuild
[meetsma waters test]$ diff specfile specfile.new
