Thank you for this information.
Following those instructions I added this to the 
(custom-set-variables   ... ) section in .emacs :

'(epg-gpg-program "gpg2")
'(epa-pinentry-mode (quote loopback))

There is no need to alter ~/.gnupg/gpg-agent.conf
because allow-loopback-pinentry is the default.

But still I am prompted twice for the passphrase when I save a
symmetrically encrypted file.

Thank you for this useful reference.
To make this work I had to add this to the (custom-set-variables   ... ) 
section in .emacs :
 '(epg-gpg-program "gpg")
 '(epa-file-cache-passphrase-for-symmetric-encryption t)

This worked, but I would never have realized that from reading the
current documentation.

Where do I go to make suggestions about improving the documentation?
