    -d  finds the first perl version where a module has been released by
        date, and not by version number (as is the default).

    --diff
        Given two versions of perl, this prints a human-readable table of
        all module changes between the two. The output format may change in
        the future, and is meant for humans, not programs. For programs, use
        the Module::CoreList API.

    -? or -help
        help! help! help! to see more help, try --man.

    -man
        all of the help

    -v  lists all of the perl release versions we got the CoreList for.

        If you pass a version argument (value of $], like 5.00503 or
        5.008008), you get a list of all the modules and their respective
        versions. (If you have the "version" module, you can also use
        new-style version numbers, like 5.8.8.)

        In module filtering context, it can be used as Perl version filter.

    -r  lists all of the perl releases and when they were released

        If you pass a perl version you get the release date for that version
        only.

    --utils
        lists the first version of perl each named utility program was
        released with

        May be used with -d to modify the first release criteria.

        If used with -v <version> then all utilities released with that
        version of perl are listed, and any utility programs named on the
        command line are ignored.

    --feature, -f
        lists the first version bundle of each named feature given

    --upstream, -u
        Shows if the given module is primarily maintained in perl core or on
        CPAN and bug tracker URL.

    As a special case, if you specify the module name "Unicode", you'll get
    the version number of the Unicode Character Database bundled with the
    requested perl versions.
