 Module::CoreList::Utils - what utilities shipped with versions of perl

SSYYNNOOPPSSIISS #

  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

 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.

 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.

 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.
