Overview
========

   GPGME provides a data abstraction that is used to pass data to the
crypto engine, and receive returned data from it.  Data can be read
from memory or from files, but it can also be provided by a callback
function.

   The actual cryptographic operations are always set within a context.
A context provides configuration parameters that define the behaviour
of all operations performed within it.  Only one operation per context
is allowed at any time, but when one operation is finished, you can run
the next operation in the same context.  There can be more than one
context, and all can run different operations at the same time.

   Furthermore, GPGME has rich key management facilities including
listing keys, querying their attributes, generating, importing,
exporting and deleting keys, and acquiring information about the trust
path.

   *Caution:* The GPGME library is not thread-safe.  It will be to some
extent in the future, but currently great care has to be taken if GPGME
is used in a multi-threaded environment.
