Thanks, these commands are really useful.

But sometimes I see public keys with custom "Version:", for example,
http://www.pgpru.com/contacts/keys/0x4D8BB49E.asc
Is it possible to change this field only by manually editing?

About "Comment:" I already know. BTW,

--comment 'hi there' (with apostrophes '')

doesn't work, works only with quotation marks ""

Thus very paranoid message should be sent via anonymous remailers and
encrypted with options:

--no-emit-version
--no-comments
--no-throw-keyids

Anything else (except removing BEGIN PGP MESSAGE)?
