time. Using this flag requires that the @var{keydata} argument of the
export function is set to @code{NULL}.
@item GPGME_EXPORT_MODE_MINIMAL
If this bit is set, the smallest possible key is exported. For OpenPGP
keys it removes all signatures except for the latest self-signatures.
For X.509 keys it has no effect.
