Folks,
I posted this script to bug 8035, but I thought I'd also send it out
here, in case others are trying to clean up their /var/pkg metadata.
The script removes manifests for packages that are no longer installed,
as well as the contents of the download directory. More details are
available in the bug:
https://defect.opensolaris.org/bz/show_bug.cgi?id=8035
A copy of the script is there, but I'm attaching one to this e-mail,
too.
