auto encrypt .gpg file

["armando.fella" <armando.fella@pi.infn.it>]

Hi all,

I inserted the following code lines in the init.el to obtain an auto
decryption on editing .gpg files and an auto encrypt at seve/close file time
with emacs-24.2-18.fc18.x86_64 on a fedora 18.

- emacs asks for the passphrase. Afterword reports the following message
after “Package pgg-gpg is obsolete!” 
- I edited the decrypted file in emacs 
- When I save it emacs reports: “Symbol’s value as variable is void:
pgg-text-mode” and forced me to quit without saving the file content

Do you have any hint to solve the problem?

Thanks a lot, Armando
