1009=head1 DESCRIPTION
1010
1011Module::CoreList::Utils provides information on which core and dual-life utilities shipped
1012with each version of L<perl>.
1013
1014It provides a number of mechanisms for querying this information.
1015
1016There is a functional programming API available for programmers to query
1017information.
1018
1019Programmers may also query the contained hash structure to find relevant
1020information.
1021
1022=head1 FUNCTIONS API
1023
1024These are the functions that are available, they may either be called as functions or class methods:
1025
1026 Module::CoreList::Utils::first_release('corelist'); # as a function
1027
1028 Module::CoreList::Utils->first_release('corelist'); # class method
1029
1030=over
1031
1032=item C<utilities>
1033
1034Requires a perl version as an argument, returns a list of utilities that shipped with
1035that version of perl, or undef/empty list if that perl doesn't exist.
1036
1037=item C<first_release( UTILITY )>
1038
1039Requires a UTILITY name as an argument, returns the perl version when that utility first
1040appeared in core as ordered by perl version number or undef ( in scalar context )
1041or an empty list ( in list context ) if that utility is not in core.
1042
1043=item C<first_release_by_date( UTILITY )>
1044
1045Requires a UTILITY name as an argument, returns the perl version when that utility first
1046appeared in core as ordered by release date or undef ( in scalar context )
1047or an empty list ( in list context ) if that utility is not in core.
1048
1049=item C<removed_from( UTILITY )>
1050
1051Takes a UTILITY name as an argument, returns the first perl version where that utility
1052was removed from core. Returns undef if the given utility was never in core or remains
1053in core.
1054
1055=item C<removed_from_by_date( UTILITY )>
1056
1057Takes a UTILITY name as an argument, returns the first perl version by release date where that
1058utility was removed from core. Returns undef if the given utility was never in core or remains
1059in core.

1063=head1 DATA STRUCTURES
1064
1065These are the hash data structures that are available:
1066
1067=over
1068
1069=item C<%Module::CoreList::Utils::utilities>
1070
1071A hash of hashes that is keyed on perl version as indicated
1072in $]. The second level hash is utility / defined pairs.
