libmodule-corelist-perl 2.12-1 (powerpc binary) in ubuntu intrepid

 Module::CoreList contains the hash of hashes
 %Module::CoreList::version, this is keyed on perl version as indicated
 in $]. The second level hash is module => version pairs.
 .
 Note, it is possible for the version of a module to be unspecified,
 whereby the value is undef, so use exists $version{$foo}{$bar} if
 that's what you're testing for.
 .
 It also contains %Module::CoreList::released hash, which has ISO
 formatted versions of the release dates, as gleaned from perlhist.
 .
 New, in 1.96 is also the %Module::CoreList::families hash, which
 clusters known perl releases by their major versions.
