The default amount is 1 em space. To change to a label gutter of 5 points
you would enter,
\labelformat{\gutter{5pt}}
\everylabel determines the type face and size of the label itself. The
default is roman face and right ragged.
�|Example:�%
The sample markup reduces the skipbefore amount, increases the labelwidth
(to suit a larger format), and changes the font for labels to 9 point bold.
Note the use of displayed math mode.
