 gpgv -- signature verification tool
 
 Synopsis
 ********
 
      gpgv
       options
       signed files
 
 DESCRIPTION
 ***********
 
 `gpgv' is the OpenPGP signature checking tool.
 
    This program is a stripped down version of `gpg' which is able only
 to check signatures. It is somewhat smaller than the fully blown `gpg'
 and uses a different (and simpler) way to check that the public keys
 used to make the signature are trustworthy. There are no options files
 and only very few options are implemented.
 
    `gpgv' assumes that all keys in the keyring are trustworthy.  By
 default it uses 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.
 
 OPTIONS
 *******
 
 `gpgv' recognizes these options:
 
 -v, -verbose
      Gives 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.
 
 -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 an 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.
 
 -ignore-time-conflict
      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 warnings.
 
 RETURN VALUE
 ************
 
 The program returns 0 if everything was fine, 1 if at least one
 signature was bad, and other error codes for fatal errors.
 
 EXAMPLES
 ********
 
 gpgv `pgpfile'
 gpgv `sigfile'
      Verify the signature of the file. The second form is used for
      detached signatures, where `sigfile' is the detached signature
      (either ASCII armored or binary) and are the signed data; if this
      is not given the name of the file holding the signed data is
      constructed by cutting off the extension (".asc", ".sig" or
      ".sign") from `sigfile'.
 
 ENVIRONMENT
 ***********
 
 HOME
      Used to locate the default home directory.
 
 GNUPGHOME
      If set directory used instead of "~/.gnupg".
 
 FILES
 *****
 
 ~/.gnupg/trustedkeys.gpg
      The default keyring with the allowed keys
