PEAR is a code repository for PHP extensions and PHP library code inspired by TeX's CTAN and Perl's CPAN. The purpose of PEAR is: * to provide a consistent means for library code authors to share their code with other developers; * to give the PHP community an infrastructure for sharing code; * to define standards that help developers write portable and reusable code; * to provide tools for code maintenance and distribution. PEAR comes bundled with PHP4. However, since it is a rapidly evolving target, not everyone who has a workable version of PHP4 has a recent enough PEAR installation. WWW: http://pear.php.net/
