RapidWeaver (RW) has plugins, stacks and themes that are described below. This RW section covers different aspects and features of RW. Their suppor website is http://realmacsoftware.com. The company is owned by founder, Dan Counsell.

First is Page Designs where different page experiments are listed.

Then I discuss RW Project files, RW Websites, an experiment with different text files and some tips and tricks

Features of Rapidweaver are discussed... snippets, stack templates, partials, app and CMS

Markdown and HTML so I compared them in one stack page. I was listing some tips and tricks, but accidentally wiped them out, playing around with partials.
Snippets I still have to figure out. Stack Templates have been dropped and Partials are the way to replicate common pages across your RW Project.

The only real App is RapidWeaver, so far. Everything plugs into it, but I'm looking for possible other apps, if they exist. CMS or Content Management System are stacks designed to let end users modify their own web sites. An RW Framework I don't really understand yet, except it's what the Foundation and Foundry are built upon.
