--list-sigs [names]
Same as --list-keys, but the signatures are
listed too.
For each signature listed, there are several
flags in between the "sig" tag and keyid. These
flags give additional information about each
signature. From left to right, they are the
numbers 1-3 for certificate check level (see
--default-cert-check-level), "L" for a local or
non-exportable signature (see --lsign-key), "R"
for a nonRevocable signature (see --nrsign-key),
"P" for a signature that contains a policy URL
(see --cert-policy-url), "N" for a signature
that contains a notation (see --cert-notation),
and "X" for an eXpired signature (see --ask-
cert-expire).
