Section is a structure describing an actual documentation section.

This can describe:

  • a general topic: think of this as an entry in a book
  • an example: a way to run a certain command
  • an application: a concrete use case for running a command. This can potentially use additional external tools, multiple commands, etc. While it is nice to keep these self-contained, it is not required.
  • a tutorial: a step-by-step guide to running a command.

Run `glaze help help-system` for more information.

	OnlyTopLevel          bool

	// only these types will be returned
	Types map[SectionType]bool

	WithoutSections []*Section
}

SectionQuery represents a query to get different types of sections.

This is used for example by the `help` command line function to render out the help sections for individual commands.

It can however also be used on its own.
