After I viewed setup.ini, I decide to write a little script to do this.
Currently, it scans all the sub-directory of cygwin local package directory,
and delete all the old files which not listed in setup.ini or setup-2.ini.

Wish it can help someone like me.=20

download it from nabble.com:
http://old.nabble.com/file/p26590979/cleanOldPackages_UTF8.sh
cleanOldPackages_UTF8.sh=20

or copy the following code to a .sh file:
