Karibou is a PHP5 MVC-like framework for developers. It is an API that helps you build your own application. It is fully object oriented, using inheritence to create new models. It uses the Smarty template engine and has XML configuration files, user authentication, permissions management, and PDO database abstraction.
ctk-nettools provides functions to deal with templates in Perl. It also provides other functions to do log, to get value from db-file (Btree or Hash), and to get the date. The principle of the templates handling is to use an HTTP server to serve the templates. There's also a cache handling to speed up templates loading and to have a copy in case of a crash of the templates server.
Puno is a PHP module (PHP5 and Linux/Unix only) that brings the OpenOffice.org UNO Programming API to the PHP userspace. You can use it to write scripts that create, modify, read, and save OpenOffice.org documents (Writer, Spreadsheet, and Drawing). You can export these documents in various formats, such as PDF or HTML.
cgi-wrap.c allows you to execute CGI scripts under a special UID/GID in a chroot environment. Unlike suexec, it does not execute arbitrary (user-)scripts but only programs which are installed and configured by the system administrator. This allows you to remove some restrictions of suexec without lowering security.
