after some downloads I ended up with 175 files with names that looked
after some attempts which I renamed with this vastly sub-optimal script
$ for i in `ls *=*`; do out=`echo $i | sed -e 's@[^*=]*@@'`; of=`echo
$out | sed 's/=//'`; mv $i $of; done
so looking for a hint on how better to have done it.
