//   summary: >
//     The Google Calendar API gives access
//     to most calendar features.
//   pages:
//   - name: Overview
//     content: &#40;== include google/foo/overview.md ==&#41;
//   - name: Tutorial
//     content: &#40;== include google/foo/tutorial.md ==&#41;
//     subpages;
//     - name: Java
//       content: &#40;== include google/foo/tutorial_java.md ==&#41;
//   rules:
//   - selector: google.calendar.Calendar.Get
//     description: >
//       ...
//   - selector: google.calendar.Calendar.Put
//     description: >
//       ...
// </code></pre>
// Documentation is provided in markdown syntax. In addition to
// standard markdown features, definition lists, tables and fenced
// code blocks are supported. Section headers can be provided and are
// interpreted relative to the section nesting of the context where
// a documentation fragment is embedded.
//
// Documentation from the IDL is merged with documentation defined
// via the config at normalization time, where documentation provided
// by config rules overrides IDL provided.
//
// A number of constructs specific to the API platform are supported
// in documentation text.
//
// In order to reference a proto element, the following
// notation can be used:
// <pre><code>&#91;fully.qualified.proto.name]&#91;]</code></pre>
// To override the display text used for the link, this can be used:
// <pre><code>&#91;display text]&#91;fully.qualified.proto.name]</code></pre>
// Text can be excluded from doc using the following notation:
// <pre><code>&#40;-- internal comment --&#41;</code></pre>
//
// A few directives are available in documentation. Note that
// directives must appear on a single line to be properly
// identified. The `include` directive includes a markdown file from
// an external source:
// <pre><code>&#40;== include path/to/file ==&#41;</code></pre>
// The `resource_for` directive marks a message to be the resource of
// a collection in REST view. If it is not specified, tools attempt
// to infer the resource from the operations in a collection:
// <pre><code>&#40;== resource_for v1.shelves.books ==&#41;</code></pre>
// The directive `suppress_warning` does not directly affect documentation
// and is documented together with service config validation.
