Data::Dumper - Displays Perl data structures, and writes them to disk as self-contained Perl code. [Perl] {oss}

Class::Eroot - An object persistence engine. Useful if you want an object to last longer than one invocation of your application. For object-oriented programmers only. [Perl] {oss}

Class::Template - Constructs "get" and "set" methods for structures and classes. Part of the Class::Eroot module. For object-oriented programmers only. [Perl] {oss}

English - Tired of all the cryptic variables $_, $', $&, and so on? The English module lets you use English names instead. It's bundled with the Perl distribution. {oss,perl}

subs - Predeclares subroutine names. The subs pragma (it's not a module) is bundled with Perl. {oss,perl}

Symbol - Manipulate Perl symbols and their names. The Symbol module is bundled with Perl. {oss,perl}

POSIX - 150 functions that POSIX dictates all good portable operating systems should have. Look here if you always wondered by Perl didn't have a tan() function, or atexit(), or what to do because POSIX sleep() requires an arguments while Perl's sleep() d {oss,perl}

AutoLoader - For module makers only. Normally, Perl modules are loaded into memory as soon as you execute them. If you want to load them only on demand, use the AutoLoader module. The AutoLoader module is bundled with Perl. Also see the SelfLoader module. {oss,perl}

AutoSplit - For module makers only. AutoLoadable modules typically split their subroutines up into separate, individually loadable files. Module designers can use AutoSplit to do this. It's bundled with Perl. Also see the AutoLoader module. {oss,perl}

diagnostics - Makes Perl warnings more verbose. The diagnostics pragma is bundled with Perl. {oss,perl}

O - The Perl Compiler. Same as the B module. {oss,perl}

overload - The overload pragma (technically it's not a module) lets you define how operations (e.g. +, ++, *=) work for your objects. It's what you do when you tell Perl how to add two complex numbers: you overload '+' so it does the right thing when it sees {oss,perl}

IO - Loads most of the IO modules at once: IO::Handle, IO::Seekable, IO::File, IO::Pipe, and IO::Socket. All of these modules are bundled with Perl.

Config - access PERL compiled-in and system configuration values.where to put binaries, how many bits your rand() function generates, the name of your operating system, whether your system supports fork(), and so on. You can access all of these values via {oss,perl}

strict - The strict pragma (it's not a module) is bundled with Perl. It lets you outlaw certain suspect programming constructs: symbolic references, barewords, and global variables. {oss,perl}

less - A not-yet-implemented pragma that will allow you to make resource tradeoffs, e.g. CPU cycles for memory. {oss,perl}

DynaLoader - If you're a module writer, you probably want to use DynaLoader to automate the dynamic loading of your module. Also see SelfLoader. {oss,perl}

Benchmark - If you want to see how fast your program is, you can't just time it with a stopwatch. Your computer is busier some moments than others, and so it's the CPU time used by your program that matters, not the total time. The Benchmark module tells you {oss,perl}

Carp - Better error warnings for your own modules. The warnings are more useful than Perl's regular warnings because they identify where your module was called from. Also see the warn() function. Carp is bundled with Perl. {oss,perl}

lib - If you've ever tried to add directories to @INC so that your modules could be found, you probably found out the hard way that you have to do it at compile time, e.g. BEGIN { push @INC, "/u/you/your_new_dir" }. The lib pragma (it's technically not {oss,perl}

Alias - If you use complex data structures or knotty object-oriented programming in Perl, and you're tired of expressions that look like $object->{property}->{attribute}, you can define a variable that means the same thing but looks a lot nicer. [Perl] {oss}

Pod::Simplify - Utilities for converting pod documentation to other formats. Pod (short for Plain Old Documentation) is a simple ASCII-based documentation format that allows Perl programs to contain their own documentation. [Perl] {oss}

Pod::Parser - A base class for parsing and selecting sections of pod documentation. Use this if you want to create your own pod2xyz program. Part of the PodParser bundle. [Perl] {oss}

Pod::Select - Dumps selected sections of raw pod documentation from an input stream. Part of the PodParser bundle. [Perl] {oss}

Pod::Text - Converts pod documentation to formatted ASCII text. Part of the PodParser bundle. [Perl] {oss}

Pod::Usage - Prints usage messages for a Perl script based on its embedded pod documentation. Part of the PodParser bundle. [Perl] {oss}

Safe - The Safe module lets you execute untrusted (or just plain untrustworthy) Perl programs inside a safe "compartment." You define the boundaries of the compartment -- whether the program is able to poke around your filesystem, or launch a denial-of-s [Perl] {oss}

SelfLoader - Like the AutoLoader, but used for dynamic loading of Perl functions that are inside your script file. Contrast with AutoLoader, which requires that the Perl functions be separate. [Perl] {oss}

SetDualVar - If you've played with Perl enough, you know there are some variables which can appear as either a number of a string depending on context. The special variable $! is an example. The SetDualVar module lets you bestow this split personality on the s [Perl] {oss}

Devel::CallerItem - For gurus only. A Devel::CallerItem object holds all the information about a specific function call on the stack. [Perl] {oss}

Devel::Regexp - For gurus only. Allows a Perl program to manipulate Perl's regular expressions as they're represented internally. [Perl] {oss}

Devel::Symdump - Provides convenient methods for inspecting Perl symbol tables. (Symbol tables are hashes that map variable names to values.) [Perl] {oss}

Devel::DumpStack - Provides functions to access and dump the current stack of subroutine calls. [Perl] {oss}

Devel::SelfStubber - Generate stub functions for a SelfLoading module. Also see the SelfLoader. [Perl] {oss}

Make - A substitute for the Unix "make" utility. Also see the cons module, in the Make directory.A [Perl] {oss}

Test::Harness - A simple interface for testing your Perl module. [Perl] {oss}

Usage - Check subroutine arguments; an easy way to ensure that, say, argument 3 is an integer, argument 1 is an object belonging to a particular class, that argument 2 isn't equal to 0, and so on. [Perl] {oss}

OS2 - Utilities and binaries for the OS/2 version Perl. [Perl] {oss}

SGI::SysCalls - Now your programs can access SGI syscalls. Not very helpful unless you have an SGI. [Perl] {oss}

Shell - Make some shell commands directly available to your Perl program. The Shell module is bundled with Perl. [Perl] {oss}

Ref - Compare and copy Perl references. Ever wonder if $a and $b were references to the same data structure? Ref tells you. [Perl] {oss}

Tie::IxHash - Now your hashes can remember the order in which elements were added. See the tie() function. ./docs/manual/html/perltie.html. [Perl] {oss}

Tie::Watch - Place a "watchpoint" on a Perl variable. This lets you identify when a variable is accessed, when it's changed, invoke a Perl/Tk callback when it changes, or trace references to it. [Perl] {oss}

HTML::Embperl - Lets you embed Perl code in your HTML documents. [Perl] {oss}

HTML::PHTML - Embed Perl in HTML; suited for FastCGI and Apache/mod_perl. [Perl] {oss}
