Overview

A List is a homogeneous set of ListItems.

The supported list types include:

:BULLET

An unordered list

:LABEL

An unordered definition list, but using an alternate RDoc::Markup syntax

:LALPHA

An ordered list using increasing lowercase English letters

:NOTE

An unordered definition list

:NUMBER

An ordered list using increasing Arabic numerals

:UALPHA

An ordered list using increasing uppercase English letters

Definition lists behave like HTML definition lists. Each list item can describe multiple terms. See RDoc::Markup::ListItem for how labels and definition are stored as list items.
