We can instead avoid parsing XML at all if we're not averse to using
`pquery`, and we can avoid the limitation of scanning the entire tree
for a single name/email by outputting the maintainers for all of the
problematic packages at once (in this case, packages output by
`gpy-py2`) in a greppable format. Not sure why pquery doesn't see
maintainers for things like automake:1.9, so this implementation is
imperfect, but here:
REPO=/var/db/repos/gentoo
for pkg in $(gpy-py2 -r "${REPO}"); do
maint=$(pquery ${pkg} --one-attr maintainers | tail -1)
if [[ ${maint} ]]; then
echo "${pkg}: ${maint}"
else
echo "${pkg}: maintainer-needed"
fi
done
