OPTIONS
       -a  lists  all  versions  of  the  given  module (or the matching modules, in case you used a

       -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)

           $ corelist -v 5.8.8 B

           B                        1.09_01

           $ corelist -v 5.8.8 /^B::/
