NAME
       Module::CoreList::Utils - what utilities shipped with versions of perl
SYNOPSIS
        use Module::CoreList::Utils;
        print $Module::CoreList::Utils::utilities{5.009003}{ptar}; # prints 1
        print Module::CoreList::Utils->first_release('corelist');
        # prints 5.008009
        print Module::CoreList::Utils->first_release_by_date('corelist');
        # prints 5.009002
DESCRIPTION
       Module::CoreList::Utils provides information on which core and dual-
       life utilities shipped with each version of perl.
       It provides a number of mechanisms for querying this information.
       There is a functional programming API available for programmers to
       query information.
       Programmers may also query the contained hash structure to find
       relevant information.
FUNCTIONS API
       These are the functions that are available, they may either be called
       as functions or class methods:
         Module::CoreList::Utils::first_release('corelist'); # as a function
         Module::CoreList::Utils->first_release('corelist'); # class method
       "utilities"
           Requires a perl version as an argument, returns a list of utilities
           that shipped with that version of perl, or undef/empty list if that
           perl doesn't exist.
       "first_release( UTILITY )"
           Requires a UTILITY name as an argument, returns the perl version
           when that utility first appeared in core as ordered by perl version
           number or undef ( in scalar context ) or an empty list ( in list
           context ) if that utility is not in core.
       "first_release_by_date( UTILITY )"
           Requires a UTILITY name as an argument, returns the perl version
           when that utility first appeared in core as ordered by release date
           or undef ( in scalar context ) or an empty list ( in list context )
           if that utility is not in core.
       "removed_from( UTILITY )"
           Takes a UTILITY name as an argument, returns the first perl version
           where that utility was removed from core. Returns undef if the
           given utility was never in core or remains in core.
       "removed_from_by_date( UTILITY )"
           Takes a UTILITY name as an argument, returns the first perl version
           by release date where that utility was removed from core. Returns
           undef if the given utility was never in core or remains in core.
DATA STRUCTURES
       These are the hash data structures that are available:
       %Module::CoreList::Utils::utilities
           A hash of hashes that is keyed on perl version as indicated in $].
           The second level hash is utility / defined pairs.
