Usage:
        pkgrecv [-s src_uri] [-a] [-d (path|dest_uri)] [-c cache_dir]
            [-kr] [-m match] [-n] [--raw] [--key src_key --cert src_cert]

        pkgrecv [-s src_repo_uri] [-d path] [-p publisher ...]
            [--key src_key --cert src_cert] [-n] --clone

Options:
        -a              Store the retrieved package data in a pkg(5) archive
                        at the location specified by -d.  The file may not
                        already exist, and this option may only be used with
                        filesystem-based destinations.

        -c cache_dir    The path to a directory that will be used to cache
                        downloaded content.  If one is not supplied, the
                        client will automatically pick a cache directory.
                        In the case where a download is interrupted, and a
                        cache directory was automatically chosen, use this
                        option to resume the download.

        -d path_or_uri  The filesystem path or URI of the target repository to
                        republish packages to.  The target must already exist.
                        New repositories can be created using pkgrepo(1).

        -h              Display this usage message.

        -k              Keep the retrieved package content compressed, ignored
                        when republishing.  Should not be used with pkgsend.

        -m match        Controls matching behaviour using the following values:
                            all-timestamps (default)
                                includes all matching timestamps (implies
                                all-versions)
                            all-versions
                                includes all matching versions
                            latest
                                includes only the latest version of each package

        -n              Perform a trial run with no changes made.

        -p publisher    Only clone the given publisher. Can be specified
                        multiple times. Only valid with --clone.

        -r              Recursively evaluates all dependencies for the provided
                        list of packages and adds them to the list.

        -s src_repo_uri A URI representing the location of a pkg(5)
                        repository to retrieve package data from.

        --clone         Make an exact copy of the source repository. By default,
                        the clone operation will only succeed if publishers in 
                        the  source  repository  are  also  present  in  the
                        destination.  By using -p, the operation can be limited
                        to  specific  publishers  which  will  be  added  to the
                        destination repository if not already present.
                        Packages in the destination repository which are not in
                        the source will be removed.
                        Cloning will leave the destination repository altered in
                        case of an error.

        --newest        List the most recent versions of the packages available
                        from the specified repository and exit.  (All other
                        options except -s will be ignored.)

        --raw           Retrieve and store the raw package data in a set of
                        directory structures by stem and version at the location
                        specified by -d.  May only be used with filesystem-
                        based destinations.  This can be used with pkgsend(1)
                        include to conveniently modify and republish packages,
                        perhaps by correcting file contents or providing
                        additional package metadata.

        --key src_key   Specify a client SSL key file to use for pkg retrieval.

        --cert src_cert Specify a client SSL certificate file to use for pkg
                        retrieval.

        --dkey dest_key Specify a client SSL key file to use for pkg
                        publication.

        --dcert dest_cert Specify a client SSL certificate file to use for pkg
                          publication.
