Class:NamedParms provides key name checking for named accessor parameters. This allows the use of a generic 'get/set' type parameterized accessor while automatically catching accidental mis-spellings and usage of uninitialized parameters. This catches a large class of programming errors without requiring a new accessor for every object parameter.

Class::ParmList is a general named parameter list parser. It handles default values, required vs allowed distinctions, optional name lexical checking, multiple retrieval, and error reporting. It also works well as a complement to Class::NamedParms.

Search::InvertedIndex is A general purpose inverted indexing system suitable for medium scale searching. By mapping 'keys' to 'indexes' it provides ultra-fast look ups of all 'indexes' containing specific 'keys'. This produces highly scalable behavior where thousands, or even millions of records can be searched extremely quickly.

CfgFile is a class for supporting the loading of a configuration file.

OSUtil is a module to help Perl programs run on mulitple platforms.

mif.pl is a Perl library to parse Frame Maker Interchange Format (MIF). It is designed to be utilized by filters.

Lingua::Stem takes lists of words an (as determined by the locale) stems them to their root form. This is primarily of use in search applications that need to be able to find conjugated forms of words as well as exact matches.

This library includes many useful routines: ReadParse which gets all form parameters and writes them into a field variable, PrintHeader which prints the Content-type text/html, HtmlTop(title, background, kopf) that simply prints a head of a HTML document, HtmlBot(title) that prints the bottom of a HTML document, SplitParam that splits a list, CgiError which prints out error messages, Check_Name which checks if a username contains dangerous signs for filenames, Get_Seconds that returns the number of seconds, lock(filehandle) that implements a locking function, unlock(filehandle) that implements a unlocking function, and more.

The libwww-perl distribution is a collection of Perl modules which provides a simple and consistent programming interface (API) to the World-Wide Web. The main focus of the library is to provide classes and functions that allow you to write WWW clients, thus libwww-perl said to be a WWW client library. The library also contain modules that are of more general use.

libwww-perl is a library of Perl packages/modules which provides a simple and consistent programming interface to the World Wide Web. This library is being developed as a collaborative effort to assist the further development of useful WWW clients and tools.

The cgi-lib.pl library makes CGI scripting in Perl easy enough for anyone to process forms and create dynamic Web content. The library features: Extremely simple to learn and easy to use, Designed for operation under Perl5 and Perl4, Very efficient, Compatibility with all CGI interactions, including File Upload, Convenient utility functions, Compatible with Perl5 security features such as taint, warnings, (command line options -Tw) and use strict, Debugging facilities, Good starting point for migration to more sophisticated libraries, etc.

The HFPM are a set of modules that accept a submitted HTML form, possibly modify the contents of the submitted fields, and output the result using e-mail, appending to a file, and/or displaying it to the user or returning an arbitrary URL. They also operate on the environmental variables passed in from the client and server.

This perl 5 library uses objects to create Web fill-out forms on the fly and to parse their contents. It provides a simple interface for parsing and interpreting query strings passed to CGI scripts. However, it also offers a rich set of functions for creating fill-out forms. Instead of remembering the syntax for HTML form elements, you just make a series of perl function calls. An important fringe benefit of this is that the value of the previous query is used to initialize the form, so that the state of the form is preserved from invocation to invocation. Everything is done through a CGI'' object. When you create one of these objects it examines the environment for a query string, parses it, and stores the results.
