PGPPASS
If this is set no connection to the pixie is attempted - it is assumed that pgp will use it as the passphrase.
Run pgp with passphrase supplied by pixie
pgp-auto [pgp options]
pgp-auto makes a connection to the passphrase pixie and then runs pgp in such a way as to ensure that it will read the passphrase from this connection rather than from the keyboard or the environment.
This is done by opening a unix-domain socket to the pixie, and then passing the file descriptor of the socket to pgp in the PGPPASSFD environment variable.
All command-line options are passed through to pgp unchanged.
