	These are the options I picked up out of the archives somewhere
and they've been working like a charm:

	--compress-algo 2
	--cipher-algo IDEA
	--digest-algo MD5
	--s2k-cipher-algo IDEA
	--s2k-digest-algo MD5
	--rfc1991
	--allow-non-selfsigned-uid

	I routinely have to decrypt traffic from First-Teams, sometimes
once a week or so, sometimes several times a day, that is pgp-2.6.x
encrypted, conventional encryption.  This was the incantation that made
it all work with gpg-1.0.3.
