Eclipse is a kind of universal tool platform - an open extensible IDE for anything and nothing in particular. The real value of Eclipse comes from tool plug-ins that "teach" Eclipse how to work with things - java files, web content, graphics, video, etc. Eclipse allows you to independently develop tools that integrate with other people's tools seamlessly.
CMME (Content Management Made Easy) is a Web content management system that aims to be easy to use, doesn't have many requirements, and is still reasonably flexible. It doesn't need a database, doesn't have extensive administrative needs, and works more or less like a wiki. New pages can be made on the fly, rather than through an administrative page.
Comments script with pagination adds comments to a website, paginating them without affecting the rest of the page content or the page URL. It can be used with multiple pages of a site, whatever the type of the page URL (modified or not with mod-rewrite). It can be set to allow only logged-in users to add comments, and has many other settings and Admin management.
