emerge-webrsync and gpg verification

Gentoo has been working on its security from very early on. One of the (many) features it supports is to allow users to validate the state of the portage tree. Ebuild signing (where developers sign the Manifest file with their key) is one of the layers offered by Gentoo, but …
