-a
  lists all versions of the given module (or the matching modules, in case you used a module regexp) in the perls Module::CoreList knows about.

-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.

# EXAMPLES

        $ corelist File::Spec
        File::Spec was first released with perl 5.005
        $ corelist File::Spec 0.83
        File::Spec 0.83 was released with perl 5.007003
        $ corelist File::Spec 0.89
        File::Spec 0.89 was not in CORE (or so I think)
        $ corelist File::Spec::Aliens
        File::Spec::Aliens  was not in CORE (or so I think)
        $ corelist /IPC::Open/
        IPC::Open2 was first released with perl 5
        IPC::Open3 was first released with perl 5
        $ corelist /MANIFEST/i
        ExtUtils::Manifest was first released with perl 5.001
        $ corelist /Template/
        /Template/  has no match in CORE (or so I think)

        B                        1.09_01
