Set the `for your eyes only' flag in the message. This causes
GnuPG to refuse to save the file unless the --output option is
given, and PGP to use a "secure viewer" with a claimed Tempest-
resistant font to display the message. This option overrides
--set-filename. --no-for-your-eyes-only disables this option.
The text should read "with a claimed Van Eck-resistant font", not "with
a claimed Tempest-resistant font". TEMPEST is the name of a NATO
standard for hardening hardware against Van Eck phreaking . Thus,
the font is not claimed to be 'Tempest-resistant' because that would
mean resisting the countermeasure. Instead it should be 'Van
Eck-resistant', because that means the font is the countermeasure.
