### Fancy enumeration lists

The enumerate package allows you to control the display of the enumeration counter. The package adds an optional parameter to the `enumerate` environment, which is used to specify the layout of the labels. The layout parameter contains an enumeration type (‘`1`’ for arabic numerals, ‘`a`’ or ‘`A`’ for alphabetic enumeration, and ‘`i`’ or ‘`I`’ for Roman numerals), and things to act as decoration of the enumeration. So, for example

>     \usepackage{enumerate}
>     ...
>     \begin{enumerate}[(a)]
>     \item ...  ...
>     \end{enumerate}

starts a list whose labels run (a), (b), (c), ...; while

>     \usepackage{enumerate}
>     ...
>     \begin{enumerate}[I/]
>     \item ...  ...
>     \end{enumerate}

starts a list whose labels run I/, II/, III/, ...

The paralist package, whose primary purpose is compaction of lists, provides the same facilities for its `enumerate`-like environments.

If you need non-stereotyped designs, the enumitem package gives you most of the flexibility you might want to design your own. The silly roman example above could be achieved by:

>     \usepackage{enumitem}
>     ...
>     \begin{enumerate}[label=\Roman{*}/]
>     \item ...  ...
>     \end{enumerate}

Note that the ‘`*`’ in the key value stands for the list counter at this level. You can also manipulate the format of references to list item labels:

>     \usepackage{enumitem}
>     ...
>     \begin{enumerate}[label=\Roman{*}/, ref=(\roman{*})]
>     \item ...  ...
>     \end{enumerate}

to make references to the list items format appear as (i), (ii), (iii), etc.

The memoir class includes functions that match those in the enumerate package, and has similar functionality for `itemize` lists.
