'''Gentoo-keys is a gpg key manager for managing
 gentoo's gpg-signing keys.  It is these keys that are
 used to verify and validate release media, etc..

 This gkeys-gpg command is a wrapper to gnupg's gpg command
 which uses the gentoo-keys keyring system to control the
 keydirs and keyrings visible to gpg
