pRuby is the ultimate glue code between PHP and Ruby which lets you use Ruby as a HTML-embedded, server-side scripting language. With pRuby, you can intermix PHP and Ruby to create dynamic web content. It features better startup speed than CGI and PHP, better execution speed than PHP, more powerful and less messier to program than PHP, cross-language function calls, and cross-language error handling.
ruby-tmpl is used for the online and offline creation of HTML, XML, and email documents. Like many other templating languages, ruby-tmpl lets you abstract the presentation from the actual content of a document. However, unlike other templating languages, ruby-tmpl also lets you perform offline processing of documents so that you can have your Web server serve static content created by templates as well as dynamic content. The templating language itself is fully XML-compliant and can safely be embedded in XML documents.
