[`fetch-servers.php`](php/fetch-servers.php) queries available servers, and [`generate-html.php`](php/generate-html.php>) generates static HTML. Static HTML is generated from the [`sites`](sites) directory to the [`output`](output) directory, which additionally contains static assets. All contents of `sites` are invoked to produce a HTML page unless they are prefixed with a `+` sign.
The current working directory of all entrypoints in the `sites` directory is anchored to `sites` itself.
This ensures that references to components are not broken when the page changes locations. For example, `require '+getenv.php';` works in both `index.php` and `about/index.php`. However, as a result, files included from such endpoints (even from the `php/` subtree) may have their parent folders shadowed when trying to use `include` themselves. Files in the same folder and in subfolders can be included, however. How PHP's `include` fallback mechanism implies this behavior is unclear.
