address@hidden gpg-agent
+Message internally calls GnuPG (the @command{gpg} command) to perform
+data encryption, and in certain cases (decrypting or signing for
+example), @command{gpg} requires user's passphrase.  Currently the
+recommended way to supply your passphrase to @command{gpg} is to use the
address@hidden program.
+
+To use @command{gpg-agent} in Emacs, you need to run the following
+command from the shell before starting Emacs.
+
address@hidden
+eval `gpg-agent --daemon`
address@hidden example
+
+This will invoke @command{gpg-agent} and set the environment variable
address@hidden to allow @command{gpg} to communicate with it.
+It might be good idea to put this command in your @file{.xsession} or
address@hidden  @xref{Invoking GPG-AGENT, , , gnupg, Using the
+GNU Privacy Guard}.
+
+Once your @command{gpg-agent} is set up, it will ask you for a
+passphrase as needed for @command{gpg}.  Under the X Window System,
+you will see a new passphrase input dialog appear.  The dialog is
+provided by PIN Entry (the @command{pinentry} command), and as of
+version 0.7.2, @command{pinentry} cannot cooperate with Emacs on a
+single tty.  So, if you are using a text console, you may need to put
+a passphrase into gpg-agent's cache beforehand.  The following command
+does the trick.
+
address@hidden
+gpg --use-agent --sign < /dev/null > /dev/null
address@hidden example
+
+The Lisp variable @code{pgg-gpg-use-agent} controls whether to use
