984Module::CoreList::Utils - what utilities shipped with versions of perl
985
986=head1 SYNOPSIS

988 use Module::CoreList::Utils;
989
990 print $Module::CoreList::Utils::utilities{5.009003}{ptar}; # prints 1

995=head1 DESCRIPTION
996
997Module::CoreList::Utils provides information on which core and dual-life utilities shipped
998with each version of L<perl>.
999
1000It provides a number of mechanisms for querying this information.
1001
1002There is a functional programming API available for programmers to query
1003information.
1004
1005Programmers may also query the contained hash structure to find relevant
1006information.
1007
1008=head1 FUNCTIONS API
1009
1010These are the functions that are available, they may either be called as functions or class methods:
1011
1012 Module::CoreList::Utils::first_release('corelist'); # as a function
1013
1014 Module::CoreList::Utils->first_release('corelist'); # class method
1015
1016=over
1017
1018=item C<utilities>
1019
1020Requires a perl version as an argument, returns a list of utilities that shipped with
1021that version of perl, or undef/empty list if that perl doesn't exist.
1022
1023=item C<first_release( UTILITY )>
1024
1025Requires a UTILITY name as an argument, returns the perl version when that utility first
1026appeared in core as ordered by perl version number or undef ( in scalar context )
1027or an empty list ( in list context ) if that utility is not in core.
1028
1029=item C<first_release_by_date( UTILITY )>
1030
1031Requires a UTILITY name as an argument, returns the perl version when that utility first
1032appeared in core as ordered by release date or undef ( in scalar context )
1033or an empty list ( in list context ) if that utility is not in core.
1034
1035=item C<removed_from( UTILITY )>
1036
1037Takes a UTILITY name as an argument, returns the first perl version where that utility
1038was removed from core. Returns undef if the given utility was never in core or remains
1039in core.
1040
1041=item C<removed_from_by_date( UTILITY )>
1042
1043Takes a UTILITY name as an argument, returns the first perl version by release date where that
1044utility was removed from core. Returns undef if the given utility was never in core or remains
1045in core.

1049=head1 DATA STRUCTURES
1050
1051These are the hash data structures that are available:
1052
1053=over
1054
1055=item C<%Module::CoreList::Utils::utilities>
1056
1057A hash of hashes that is keyed on perl version as indicated
1058in $]. The second level hash is utility / defined pairs.
