/*
An `OxDoc` comment is an inline or multi-line comment that starts with `@`:
```
//@ ...
/*@
...
*&#047;
```
The syntax is simple: almost every line has the form `name <type> summary`. If
it doesn't, its meaning depends on its context.
*/

/*
If the first line of the comment doesn't match `name <type> summary`, it is a
section definition. Here, it marks a section named 'Primitives'.

/*
This inline comment documents an item by providing its name, type and one-line
summary.

/*
In a multiline comment, lines that follow the inital definition are indented, as
they refer to the item defined in the line above. Lines that don't match `name
<type> summary` are parsed as a description. Like the summary, the description
can contain some `markdown` (see Ox.parseMarkdown).

A line that starts with `#` is an inline comment that will be ignored by the
parser.
The following lines document properties of the `My.favorites` object. This
example shows all possible values for `type`. These values can be shortened —
it's sufficient to specify their first character.
A line that starts with `>` is an inline test statement, followed by the
expected result. (Yes, it's that simple!)
