parent allows you to both load one or more modules, while setting up inheritance from those modules at the same time. Mostly similar in effect to: package Baz; BEGIN { require Foo; require Bar; push @ISA, qw(Foo Bar); }
This package contains Pod::Man and Pod::Text modules which convert POD input to *roff source output, suitable for man pages, or plain text. It also includes several sub-classes of Pod::Text for formatted output to terminals with various capabilities.
Suidperl is a setuid binary copy of perl that allows for (hopefully) more secure running of setuid perl scripts.
Since Perl 5.8, thread programming has been available using a model called interpreter threads which provides a new Perl interpreter for each thread, and, by default, results in no data or state information being shared between threads. (Prior to Perl 5.8, 5005threads was available through the Thread.pm API. This threading model has been deprecated, and was removed as of Perl 5.10.0.) As just mentioned, all variables are, by default, thread local. To use shared variables, you need to also load threads::shared.
By default, variables are private to each thread, and each newly created thread gets a private copy of each existing variable. This module allows you to share variables across different threads (and pseudo-forks on Win32). It is used together with the threads module. This module supports the sharing of the following data types only: scalars and scalar refs, arrays and array refs, and hashes and hash refs.
Version objects were added to Perl in 5.10. This module implements version objects for older version of Perl and provides the version object API for all versions of Perl. All previous releases before 0.74 are deprecated and should not be used due to incompatible API changes. Version 0.77 introduces the new 'parse' and 'declare' methods to standardize usage. You are strongly urged to set 0.77 as a minimum in your code.
