title: A subfile!

I am a little piece of content

# With a title!

And things...

:::{if=cat}

:::

``` {.python .run}
# I set my own flags!
ctx.set_flag("cat", True)
```

``` {.python .run}
println(f"The subdocument's title is \n\n# {ctx.get_metadata('title')}")
println()
println(f"The subdocument's subtitle is \n\n## {ctx.get_metadata('subtitle')}")
```

``` {.python .run}
ctx.set_metadata("language", "cs")
```

Tak toto je "v prádelně" pánové!

``` {.python .run}
ctx.set_metadata("language", "en")
```

This is "in a laundry room" gentlemen!


``` {.python .run}
ctx.unset_metadata("language")
```

I am a duck.

:::{if=cat}
This should be only shown to included cats.
