User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (gnu/linux)

I've just written the little Elisp script below which auto-generates
the <foo>-readme.txt and archive-contents file and found one problem
with the current setup:

This script can't find the description of the org package because it's
not installed in elpa/packages.  So if we remove the foo-readme.txt and
archive-contents from the Bzr and then rebuild those files during
package-update.sh we're all set, but if we want to keep those files in
the Bzr it's a bit more cumbersome.
I'm not sure under which circumstances package-update.sh is run, so
since it currently doesn't run Emacs, I haven't changed it to run

Could someone figure out what to do with package-update.sh and ideally
remove all the *-readme.txt (and the archive-contents) files?
