     "GnuPG Made Easy (GPGME) is a library designed to make access to GnuPG
easier for applications.  It provides a High-Level Crypto API for encryption,
decryption, signing, signature verification and key management.  Currently
it uses GnuPG as its backend but the API isn't restricted to this engine.

Because the direct use of GnuPG from an application can be a complicated
programming task, it is suggested that all software should try to use GPGME
instead.  This way bug fixes or improvements can be done at a central place
and every application benefits from this.")

and aims to solve the problem that a gpg keyring is a binary blob that's hard
for multiple people to collaboratively edit.

With jetring, changesets can be submitted, reviewed to see exactly what they
will do, applied, and used to build a keyring.  The origin of every change made
to the keyring is available for auditing, and gpg signatures can be used for
integrity guarantees.")
