"""Faux CMS: bulk website content stored in templates and document files.
Rationale: Many websites have a CMS and store the majority of their website
content in a relational database eg. WordPress or Wagtail. That's useful
because various people can easily be given access to edit the website. The
downside is that is application complexity - the management of who change
what, when it changed and what changed becomes an application concern. At
the other end of the spectrum, we have files that are checked into a Git
repository - we get the precise who/what/when out of the box with Git, but
require you to have some technical knowledge and appropriate access to
commit. Since you're committing to a code repository, this also opens up the
possibility to break things you couldn't break via a CMS.
This view serves most of the textual pages and documents on
sfconservancy.org. It works a little like Apache serving mixed PHP/static
files - it looks at the URL and tries to find a matching file on the
filesystem. If it finds a template, it renders it via Django's template
infrastructure. If it finds a file but it's not a template, it will serve
the file as-is.
