        pkgrecv [-s src_repo_uri] --newest 

Options:

        -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.

                        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

        -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

                                includes all matching timestamps, not just

                                latest (implies all-versions)

                            all-versions

                                includes all matching versions, not just latest

        -n              Perform a trial run with no changes made.

        -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.

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