Here it goes:

-- start --

for i in $DBPATH/*; do
   if [[ -f $i/depends ]]; then
     cat $i/depends >> $i/desc
     rm $i/depends
-- end --

If you are going to test these patches before they are accepted to 
master, I suggest you copy your local db elsewhere and change DBPATH in 
that script.  Then you can use pacman with --dbpath (but do not do 
anything that modifies the local db...)
