NAME

Perl4::CoreLibs - libraries historically supplied with Perl 4

DESCRIPTION

This is a collection of ".pl" files that were bundled with the Perlcore until core version 5.15.1. Relying on their presence in the coredistribution is deprecated; they should be acquired from this CPANdistribution instead. From core version 5.13.3 until their removal, thecore versions of these libraries emit a deprecation warning when loaded.The CPAN version does not emit such a warning.

The entire Perl 4 approach to libraries was largely superseded in Perl5.000 by the system of module namespaces and ".pm" files. Most ofthe libraries in this collection predate Perl 5.000, but a handful werefirst introduced in that version. Functionally, most have been directlysuperseded by modules in the Perl 5 style. These libraries should notbe used by new code. This collection exists to support old Perl programsthat predate satisfactory replacements.

Most of these libraries have not been substantially maintained in thecourse of Perl 5 development. They are now very antiquated in style,making no use of the language facilities introduced since Perl 4.They should therefore not be used as programming examples.
