How to reinstall everything?

[Eliot Moss]

Dear cygwin-ers -- I've moved to new computer and want to install the same packages I had before. 
Is there a way to tell setup from the command line to re-install all packages from my local package 
directory?  (Things are mostly installed, but not working entirely properly, and it is tedious to go 
through an mouse-click every item to "Reinstall"!)
