Site Blueprint

I'm thinking of a module that self-documents the site. Not the documentation generated for the API, etc. Higher level. The audience would be an incoming developer or maintainer, etc. not familiar with the site.

The idea is for it to compile through examination a list of custom and contributed modules, blocks, views, templates, taxonomies, content types, permissions, hooks, overrides, etc., of things not provided by core, noting whether they are contributed, custom, created via the UI or in code, etc.

The output in one place and one nice expandable bundle, perhaps a graphical summary representation too, and perhaps with the ability to have a formatted print as well.
