PySite is not a CMS in the traditional sense. Rather, you manage the contents of a Web site via a file manager interface, which gives you access to all settings (pages, styles, plugins, etc.). Compose your pages with Jinja templates, and edit your code comfortably with syntax highlighting in the ACE editor. You may write your stylesheets in Sass and let the integrated compiler write CSS files. PySite also contains a facility to manage virtual mailboxes, in case you maintain your own SMTP and IMAP server, e.g. with Postfix and Dovecot.
Jinja24Doc is a lightweight documentation generator for Python modules with jinja2 templates. It is part of the Poor HTTP group tools (WSGI connector, WSGI/HTTP Server, and mod_python connector). It can load modules and get documentation for its items. No configuration is needed, only jinja2 templates.
