       gpgv -- signature verification tool

       gpgv  [options]	[signed files]

       gpgv is the OpenPGP signature checking tool.

       This program is a stripped down version of gpg which is only able to check signatures.  It
       is somewhat smaller than the full blown gpg and uses a different (and more simple way)  to
       check that the public keys used to made the signature are trustworth.  There is no options
       files and only very few options are implemented.

       gpgv assumes that all keys in the keyring are trustworty.  It uses by  default  a  keyring
       named  trustedkeys.gpg which is assumed to be in the home directory as defined by GnuPG or
       set by an option or an environment variable.  An option may be  used  to  specify  another
       keyring or even multiple keyrings.

       gpgv recognizes these options:

       -v, --verbose
		 Give more information during processing. If used twice, the input data is listed
		 in detail.

       -q, --quiet
		 Try to be as quiet as possible.

       --keyring file
		 Add file to the list of keyrings.  If file begins with  a  tilde  and	a  slash,
		 these	are  replaced  by  the HOME directory. If the filename does not contain a
		 slash, it is assumed to be in the home-directory ("~/.gnupg" if --homedir is not
		 used).  The filename may be prefixed with a scheme:

		 "gnupg-ring:" is the default one.

		 It might make sense to use it together with --no-default-keyring.

       --homedir directory
		 Set  the  name  of the home directory to directory If this option is not used it
		 defaults to "~/.gnupg". It does not make sense to use this in	a  options  file.
		 This also overrides the environment variable "GNUPGHOME".

       --status-fd n
		 Write	special status strings to the file descriptor n.  See the file DETAILS in
		 the documentation for a listing of them.

       --logger-fd n
		 Write log output to file descriptor n and not to stderr.

		 GnuPG normally checks that the timestamps associated with  keys  and  signatures
		 have  plausible  values.   However, sometimes a signature seems to be older than
		 the key due to clock problems.  This option makes these checks just a warning.

       The program returns 0 if everything was fine, 1 if at least one	signature  was	bad,  and
       other error codes for fatal errors.

       gpgv pgpfile

       gpgv sigfile [files]
		 Verify  the  signature  of the file. The second form is used for detached signa-
		 tures, where sigfile is the detached signature (either ASCII armored or  binary)
		 and [files] are the signed data; if this is not given the name of the file hold-
		 ing the signed data is constructed by cutting off the extension (".asc",  ".sig"
		 or ".sign") from sigfile.

       HOME	 Used to locate the default home directory.

       GNUPGHOME If set directory used instead of "~/.gnupg".

		 The default keyring with the allowed keys
