If the foo were that simple, someone would have done it long ago. It
needs to take into account updates/.
I have sent my script directly to wolf31o2 some days ago thinking that
the exact technical details can considered spam for the majority
subscribed on the list, but for completeness I'm attaching in in this
e-mail.
It works comparing two different portage snapshots that it can also
download.
Best,
Yuri.
I was planning to have this cron'd on lark (cvs.gentoo.org) and run
against the cvs history file.

# Purpose: This script analyzes the cvs history file in an attempt to locate package
# additions and removals. It takes 3 arguments; two of which are optional. It needs
# the path to the history file to read. If a start_date is not provided it will read
# the entire file and match any addition/removal. If you provide a start date it will
# only match thins that are after that start_date. If you provide an end date you can
# find matches over date ranges. If an end date is not provided it defaults to now()
