Numbered and bulletted lists are very common in documents.
The enumerate and itemize environments
are used for creating such lists. Thus, a numbered
list begins with \begin{enumerate} and ends
with \end{enumerate}. The items of the list
go between these. The start of each item should be
marked with the command \item, which can
be thought of as generating the item number. \begin{itemize} and
\end{itemize} are used in exactly the same way to
create bulletted lists. Lists can be nested inside one another,
and LATEX will indent the lists properly to show the
nesting. For numbered lists, the style of numbering
(numbers, letters, or roman numerals) changes depending
on the level of nesting.
