define Package/gnupg/description
 GnuPG is GNU's tool for secure communication and data storage.
 It can be used to encrypt data and to create digital signatures.
 It includes an advanced key management facility and is compliant
 with the proposed OpenPGP Internet standard as described in RFC2440.
 .
 GnuPG does not use any patented algorithms so it cannot be compatible
 with PGP2 because it uses IDEA (which is patented worldwide).
endef

define Package/gpgv/description
 GPGv is a stripped down version of GnuPG that only checks signatures.
 .
 GnuPG does not use any patented algorithms so it cannot be compatible
