The Guava tools are a set of Perl scripts for HTML pre-processing. You can create multi-page documents with contents tables, or use templates to give a consistent look to a set of pages. All output is passed through the C preprocessor, so you can use directives such as #include, #define and #if. There are also built-in macros for producing dates, cross references, etc.
PHP Content Management System (phpCMS) makes it possible to need only one template for your whole Web site. It allows you to provide dynamic menus with unlimited levels, and use templates and sub-templates without a database. It is search engine-friendly and proxy-friendly, as the pages it generates can not be distinguished from static HTML pages. PHP code can be added to any template and content file with an optional module. It supports the caching of parsed pages and gzip compression.
RADpage is a rapid application development system for dynamic, data-driven Web applications. It directly operates inside the browser without requiring a client-dependent development environment. RADpage comes as an Apache module or a CGI, includes a powerful HTML/XML like object-oriented programming language called heitml (pronounced "Hi-TML"), and more than 150 Web application components. Development is done on a fully functional application instead of requiring the edit-save-browse cycle associated with conventional client-side development environments. The RADpage editor stores application pages in readable well-formed XML or upon request in HTML for editing with HTML editors.
