1051=head1 DESCRIPTION
1052
1053Module::CoreList::Utils provides information on which core and dual-life utilities shipped
1054with each version of L<perl>.
1055
1056It provides a number of mechanisms for querying this information.
1057
1058There is a functional programming API available for programmers to query
1059information.
1060
1061Programmers may also query the contained hash structure to find relevant
1062information.
1063
1064=head1 FUNCTIONS API
1065
1066These are the functions that are available, they may either be called as functions or class methods:
1067
1068 Module::CoreList::Utils::first_release('corelist'); # as a function
1069
1070 Module::CoreList::Utils->first_release('corelist'); # class method
1071
1072=over
1073
1074=item C<utilities>
1075
1076Requires a perl version as an argument, returns a list of utilities that shipped with
1077that version of perl, or undef/empty list if that perl doesn't exist.
1078
1079=item C<first_release( UTILITY )>
1080
1081Requires a UTILITY name as an argument, returns the perl version when that utility first
1082appeared in core as ordered by perl version number or undef ( in scalar context )
1083or an empty list ( in list context ) if that utility is not in core.
1084
1085=item C<first_release_by_date( UTILITY )>
1086
1087Requires a UTILITY name as an argument, returns the perl version when that utility first
1088appeared in core as ordered by release date or undef ( in scalar context )
1089or an empty list ( in list context ) if that utility is not in core.
1090
1091=item C<removed_from( UTILITY )>
1092
1093Takes a UTILITY name as an argument, returns the first perl version where that utility
1094was removed from core. Returns undef if the given utility was never in core or remains
1095in core.
1096
1097=item C<removed_from_by_date( UTILITY )>
1098
1099Takes a UTILITY name as an argument, returns the first perl version by release date where that
1100utility was removed from core. Returns undef if the given utility was never in core or remains
1101in core.

1105=head1 DATA STRUCTURES
1106
1107These are the hash data structures that are available:
1108
1109=over
1110
1111=item C<%Module::CoreList::Utils::utilities>
1112
1113A hash of hashes that is keyed on perl version as indicated
1114in $]. The second level hash is utility / defined pairs.
