Blender is a free 3D animation studio. It includes tools for modeling, sculpting, texturing (painting, node-based shader materials, or UV mapped), UV mapping, rigging and constraints, weight painting, particle systems, simulation (fluids, physics, and soft body dynamics and an external crowd simulator), rendering, node-based compositing, and non linear video editing, as well as an integrated game engine for real-time interactive 3D, and game creation and playback with cross-platform compatibility.
Perl text2html is an HTML 4.01/CSS2 project that converts pure plain text files into very informative and professional looking HTML documentation pages. The text files require no markup whatsoever; just naturally written text. This utility predates the now similar Python-based asciidoc.
htmLawed is a PHP script that makes input text more secure, HTML standards-compliant, and suitable in general from the viewpoint of a Web-page administrator, for use in the body of HTML 4 or XHTML 1 or 1.1 documents. It is a customizable HTML/XHTML filter, processor, purifier, and sanitizer. It can ensure that HTML tags are balanced and properly nested tags, neutralize code that may be used for cross-site scripting (XSS) attacks, and limit the allowed HTML elements, tags, attributes, or URL protocols.
perl-depends is a tool that roughly determines the modules a Perl program uses. Perl evaluates "use" commands at compile time and stores the loaded module information into the %INC variable. By examining the loaded modules and comparing them against the standard Perl modules, the external module dependencies can be roughly estimated.
