Typically, \verb|<commands>| will contain a rule or leaders. +If the text spans more than one line, then there will be several +chunks to be undelined (one per line). + +You can use the following macros in \verb|<commands>|. + +\begin{desc} +\verb|\ulwidth| +\end{desc} + +The width of the text block to be underlined.

See +an example below. + +\begin{desc} +\verb|\ulstarttype|\qquad\verb|\ulendtype| +\end{desc} + +Macros storing the values described above, so that you can use +\LaTeX{} conditionals (or \TeX{} ones).

Just set +the offset to a value larger than 0pt, as for example .1 em. This +value is added ($\times$2) to \verb|\ulwidth|, but no space is added +to the text (which can be done with the \verb|gap| key). Of course, +you can still do finer adjustments in the definition of the underline, +as shown in the samples below. You can use \verb|xoffset-start| and +\verb|xoffset-end| to set the corresponding values separately. + +\item[\texttt{gap}] It is equivalent to the outer space in +\verb|\sodef|. This value is \textit{not} added to \verb|\ulwidth|. +You can use \verb|gap-start| and \verb|gap-end| to set the +corresponding values separately. + + +\item[\texttt{hyphens}] Sometimes excluding the hyphen from the +underlined text could make sense. Default is \verb|hyphens=include| +but you can set it to \verb|hyphens=exclude|. + + +\item[\texttt{overdraw}] By default underlines are drawn before the +text is typeset (with \verb|\rlap|), so that they are placed behind. +However, it can be drawn after (with \verb|\llap|), on top the text, +with \verb|overdraw| or, equivalently, \verb|overdraw=true| (default +is \verb|overdraw=false|). +\end{description} + +\begin{desc} +\verb|\ulpostolerance| +\end{desc} + +The current algorithm is based on changes of the $y$ coordinate of +savepos and therefore presumes a regular baseline.
