One way of structuring your information is by way of enumeration or summing up
items. The itemize command looks like this:

\shortsetup{startitemize}

For example:

\startbuffer
\startitemize[R,packed,broad]
\item Hasselt was founded in the 14th century.
\item Hasselt is known as a so called Hanze town.
\item Hasselt's name stems from a tree.
\stopitemize
\stopbuffer

\typebuffer

Within the \type{\start ... \stopitemize} pair you start a new item with
\type{\item}. The space after \type{\item} is required. In the example above
\type{R} specifies Roman numbering and \type{packed} keeps line spacing to a
minimum. The parameter \type{broad} takes care of the spacing between item
separator and item. The example would produce:

\getbuffer

Items can be defined in a more structured way:

\startbuffer
\startitemize[R,packed,broad]
\startitem Hasselt was founded in the 14th century. \stopitem
\startitem Hasselt is known as a so called Hanze town. \stopitem
\startitem Hasselt's name stems from a tree. \stopitem
\stopitemize
\stopbuffer

\typebuffer

The bracket pair contains information on item separators and local set up
variables.

\placetable

  {\starttable[|l|l|]
  \HL

  \NC 1            \NC $\bullet$            \NC\FR
  \NC 2            \NC $-$                  \NC\MR
  \NC 3            \NC $\star$              \NC\MR
  \NC $\vdots$     \NC $\vdots$             \NC\MR
  \NC n            \NC 1 2 3 4 $\cdots$     \NC\MR
  \NC a            \NC a b c d $\cdots$     \NC\MR
  \NC A            \NC A B C D $\cdots$     \NC\MR
  \NC r            \NC i ii iii iv $\cdots$ \NC\MR
  \NC R            \NC I II III IV $\cdots$ \NC\LR
  \HL
  \stoptable}

You can also define your own item separator by means of \type{\definesymbol}. For
example if you try this:

\startbuffer
\definesymbol[5][$\clubsuit$]

\startitemize[5,packed]
\item Hasselt was built on a riverdune.
\item Hasselt lies at the crossing of two rivers.
\stopitemize
\stopbuffer

\typebuffer

You will get:

\getbuffer

If you want to have a sort of head within an enumeration you should use
\type{\head} instead of \type{\item}.

\startbuffer
Hasselt lies in the province of Overijssel and there are a number
of customs that are typical of this province.

\startitemize

\head kraamschudden \hfill (child welcoming)

      When a child is born the neighbours come to visit the new
      parents. The women come to admire the baby and the men come to
      judge the baby (if it is a boy) on other aspects.
      The neighbours will bring a {\em krentenwegge} along. A
      krentenwegge is a loaf of currant bread of about 1 \unit{Meter}
      long. Of course the birth is celebrated with {\em jenever}.

\head nabuurschap (naberschop) \hfill (neighbourship)

      Smaller communities used to be very dependent on the
      cooperation among the members for their well being. Members of
      the {\em nabuurschap} helped each other in difficult times
      during harvest times, funerals or any hardship that fell upon
      the community.

\head Abraham \& Sarah  \hfill (identical)

      When people turn 50 in Hasselt it is said that they see Abraham
      or Sarah. The custom is to give these people a {\em speculaas}
      Abraham or a Sarah. Speculaas is a kind of hard spiced biscuit.

\stopitemize
\stopbuffer

\typebuffer

The \type{\head} can be set up with \type{\setupitemize}. In case of a page
breaking a \type{\head} will appear on a new page. (The \type {\unit{Meter}}
command is explained in \in {chapter} [units].)

The example of old customs will look like this:

\getbuffer

The set up parameters of itemize are described in \in {table} [tab:itemizesetup].

\placetable

  \HL
  \stoptable}

You can use the set up parameters in \type{\startitemize}, but for reasons of
consistency you can make them valid for the complete document with
\type{\setupitemize}.

The parameter \type{columns} is used in conjunction with
a (written) number. If you type this:

\startbuffer
\startitemize[n,columns,four]
\item Achter 't Werk
.
.
.
\item Justitiebastion
\stopitemize
\stopbuffer

\typebuffer

\page[bigpreference]

You will get:

\startbuffer
\startitemize[n,packed,columns,four,broad]
\item Achter 't Werk
\item Baangracht
\item Brouwersgracht
\item Eikenlaan
\item Eiland
\item Gasthuisstraat
\item Heerengracht
\item Hofstraat
\item Hoogstraat
\item Julianakade
\item Justitiebastion
\item Kaai
\item Kalverstraat
\item Kastanjelaan
\item Keppelstraat
\stopitemize
\stopbuffer

\bgroup
\getbuffer
\egroup

Sometimes you want to continue the enumeration after a short intermezzo. Then you
type for example \type{\startitemize[continue]} and numbering
will continue and all other preferences are kept.

\startbuffer
\startitemize[continue]
\item Markt
\item Meestersteeg
\item Prinsengracht
\item Raamstraat
\item Ridderstraat
\item Rosmolenstraat
\item Royenplein
\item Van Nahuijsweg
\item Vicariehof
\item Vissteeg
\item Watersteeg
\item Wilhelminalaan
\item Ziekenhuisstraat
\stopitemize
\stopbuffer

\getbuffer

The parameter \type{broad} enlarges the horizontal space between item separator
and itemtext.

\shortsetup{setupitemize}

An itemize within an itemize is automatically typeset in a correct way. For
example if you type:

\startbuffer
In the Netherlands the cities can determine the height of a number of
taxes. So the cost of living can differ from town to town. There are
differences of up to 50\% in taxes such as:

\setupitemize[2][width=5em]
\startitemize[n]

\item[estate tax] real estate tax

      The real estate tax is divided into two components:

      \startitemize[a,packed]
      \item the ownership tax
      \item the tenant tax
      \stopitemize

      If the real estate has no tenant the owner pays both components.

\item dog licence fee

      The owner of one or more dogs pays a fee. When a dog has died
      or been sold the owner has to inform city hall.

\stopitemize
\stopbuffer

\typebuffer

then the horizontal space between item separator and text at the second level of
itemizing is set with \type{\setupitemize[2][width=5em]}.

The example will look like this:

\start
\getbuffer
\stop

You can refer to an item if you give it a label (see \type{\item[estate tax]}).
If you then type:

\startbuffer
\in{In item}[estate tax] we discussed one of the income sources of Hasselt.
\stopbuffer

\typebuffer

You'll get a reference to that item:

\getbuffer
