Extract herds & maintainers' email from a Gentoo metadata.xml file

xmlstarlet sel -t -m '/pkgmetadata/herd' -v . -n -t -m '/pkgmetadata/maintainer' -v email metadata.xml
The command requires app-text/xmlstarlet but it otherwise self-contained. It extracts all the herds and all the maintainers' email for a given package and is what I'm using on the Tinderbox to make it easier for me to report bugs.
Sample Output
$ xmlstarlet sel -t -m '/pkgmetadata/herd' -v . -n -t -m '/pkgmetadata/maintainer' -v email /usr/portage/app-crypt/ekeyd/metadata.xml
no-herd
