NAME

6       Perl4::CoreLibs - libraries historically supplied with Perl 4
7

DESCRIPTION

9       This is a collection of ".pl" files that were bundled with the Perl
10       core until core version 5.15.1.  Relying on their presence in the core
11       distribution is deprecated; they should be acquired from this CPAN
12       distribution instead.  From core version 5.13.3 until their removal,
13       the core versions of these libraries emit a deprecation warning when
14       loaded.  The CPAN version does not emit such a warning.
15
16       The entire Perl 4 approach to libraries was largely superseded in Perl
17       5.000 by the system of module namespaces and ".pm" files.  Most of the
18       libraries in this collection predate Perl 5.000, but a handful were
19       first introduced in that version.  Functionally, most have been
20       directly superseded by modules in the Perl 5 style.  These libraries
21       should not be used by new code.  This collection exists to support old
22       Perl programs that predate satisfactory replacements.
23
24       Most of these libraries have not been substantially maintained in the
25       course of Perl 5 development.  They are now very antiquated in style,
26       making no use of the language facilities introduced since Perl 4.  They
27       should therefore not be used as programming examples.
