To handle @acronym{PGP} and @acronym{PGP/MIME} messages, you have to
install an OpenPGP implementation such as GnuPG. The Lisp interface
-to GnuPG included with Gnus is called PGG (@pxref{Top, ,PGG, pgg, PGG
-Manual}), but Mailcrypt and gpg.el are also supported.
+to GnuPG included with Emacs is called EasyPG (@pxref{Top, ,EasyPG,

+PGG Manual}), Mailcrypt, and gpg.el are also supported.

To handle @acronym{S/MIME} message, you need to install OpenSSL. OpenSSL 0.9.6

commands will not mark an article as expirable, even if the group has
auto-expire turned on.
+@vindex gnus-mark-copied-or-moved-articles-as-expirable
+The expirable marks of articles will be removed when copying or moving
+them to a group in which auto-expire is not turned on. This is for
+preventing articles from being expired unintentionally. On the other
+hand, to a group that has turned auto-expire on, the expirable marks of
+articles that are copied or moved will not be changed by default. I.e.,
+when copying or moving to such a group, articles that were expirable
+will be left expirable and ones that were not expirable will not be
+marked as expirable. So, even though in auto-expire groups, some
+articles will never get expired (unless you read them again). If you
+don't side with that behavior that unexpirable articles may be mixed
+into auto-expire groups, you can set
+@code{gnus-mark-copied-or-moved-articles-as-expirable} to a
+non-@code{nil} value. In that case, articles that have been read will
+be marked as expirable automatically when being copied or moved to a
+group that has auto-expire turned on. The default value is @code{nil}.
