-%
-%  A style file to provide various types of underlining that can stretch
-%  between words and be broken across lines.  Use with LaTeX or plain TeX.
-%  In LaTeX this style replaces italics with underlining in \em-phasized text.
-%  It is most suitable for simple text such as {\em ibid.} or {\em \LaTeX:
-%  A Document Preparation System\/} that may need to be underlined in a
-%  manuscript submitted for publication.  This is ONLY to be used when emphasis
-%  is delimited by braces.  A declaration \normalem (or the \usepackage
-%  option "normalem") restores the normal \em behavior.
-%
-%  Full instructions appear after \endinput.  In summary:
-%    \uline{important}   underlined text
-%    \uuline{urgent}     double-underlined text
-%    \uwave{boat}        wavy underline
-%    \sout{wrong}        line drawn through word
-%    \xout{removed}      marked over with //////.
-%    {\em phasized\/}  | In LaTeX, by default, these are underlined; use
-%    \emph{asized}     | \normalem or [normalem] to restore italics
-%    \useunder{\uwave}{\bfseries}{\textbf}
-%                        use wavy underline in place of bold face

-
-ULEM is a package for LaTeX or plain TeX which provides various types of
-underlining that can stretch between words and be broken across lines.
-In LaTeX this style replaces italics with underlining in emphasized text
-given by \em or \emph -- but only if the text is delimited by braces.  A
-declaration \normalem (or the \usepackage option [normalem]) restores the
-normal \em behavior.  For underlining in plain TeX, \input ulem.sty, and
-use the \uline command.
-
-Unlike regular underlining, ulem allows line breaks, and even primitive
-hyphenation, within the underlined text; but it is far from perfect. It is
-most suitable for simple text like  {\em \LaTeX: A document preparation
-system\/}  that may need to be underlined in a manuscript submitted for
-publication.  Again, ulem will only replace \em and \emph when the text is
-delimited by explicit braces.
-
-The thickness of the underline rule is given by \ULthickness; use
-\renewcommand or \def (not \setlength) to change it.  The depth of the
-underline is controlled by the length \ULdepth.  The default value is a
-special flag which lets the current font control the depth.  You can set
-a particular value to \ULdepth (using \setlength) to force a particular
-depth, either locally for a special purpose, or for the document as a
-whole.  See the definition of \sout.
-
-Every word is typeset in an underlined box, so automatic hyphenation is
-normally disabled, but explicit discretionary hyphens (\-) will still be
-obeyed.  Several text-formatting commands are specially supported within
-the underlining:  \-, \ , ~, \\, \newline, \linebreak, \nolinebreak,
-\penalty, \hskip, \hspace, \hfil, \hfill, \hss.  Displayed math and \par
-are deliberately not supported to aid in the detection of runaway arguments
-(missing braces).  The special commands do have a problem: they end a
-group so any local assignments are lost.  
-
-The underlines continue between words, and stretch just like ordinary
-spaces do.  Since spaces delimit words, there may be some difficulty
-with syntactical spaces (e.g. "2.3 pt"). Some effort is made to handle
-such cases, but sometimes (such as \let\x= y) the space is interpreted
-incorrectly. You can usually solve the problem by enclosing the offending
-command in braces or in a macro (\newcommand\xeqy{\let\x= y}), but...
-
-One important incompatibility with braces and macro replacement:
-ALL THE TEXT IN BRACES OR COMING FROM A MACRO IS TYPESET IN A BOX.
-That is, braces will suppress stretching and linebreaks in the text they
-enclose.  Moreover, the specially-taken-care-of commands \-, \\, \newline
-and \linebreak are usually ignored if they appear inside extra braces.
-They operate only when the braces delimit a command parameter without
-introducing a level of grouping.  (Even though braces delimiting command
-parameters do not normally imply grouping, many commands will add their
-own grouping.)  Thus, you should try to limit inner braces to short bits of
-text or for delimiting parameters to commands. For emergency repairs, see
-the "Marat/Sade" example below.  Syntactical spaces inside braces never
-cause a problem, nor do spaces in math mode.
-
-Text produced by expansion of a command (macro) is boxed too, but \\, \
-and \- still work properly in the expansion text:
-        \newcommand\iff{if and only if} {\em \iff}
-does not allow any stretching or linebreaking between words, but
-        \newcommand\iff{if\ and\ only\ if} {\em \iff}
-allows stretching and linebreaking.  There is a problem though:  the
-\  between words closes a group and any local assignments will be lost,
-in particular, font changes and color changes.
-
-This loss of local assignments will break some other standard commands,
-(e.g., \cite) which produce multiple `words' using local assignments.
-The way to protect such commands is to bury them in an \mbox:
-        {\em every\-one agrees~\mbox{\cite{you,me}}.}
-
-Nested \em commands produce multiple underlining, but heed the warnings
-about braces above.  To get italics without underlining, use \it.  Nesting
-of other types of underline is also possible, but the `underlines' may
-overlap.
-
-HERE IS A SIMPLE EXAMPLE.
-
-\noindent 'Twas {\em brillig\/} and the {\em slithy~toves\/}
-did {\em gyre\/} and {\em gim\-ble\/} in the {\em wabe,\\[2pt] }
-All {\em mim\-sey\/} were the {\em boro\-goves\/} and
-the {\em mome raths outgrabe}.
-
-HERE IS A DIFFICULT EXAMPLE.
-
-\usepackage{ulem}
-\setlength\textwidth{3.3in}
-\begin{document}
-% \large
-No, I did {\em not} act in the movie {\em \emph{The} %    <<<<<<< Nested
-\emph{Persecu}\-\emph{tion} \emph{and} \emph{Assassination} \emph{of}
-\emph{Jean-Paul} \emph{Marat}, as per\-formed by the Inmates
-of the Asylum of Charenton under the Direc\-tion of the
-Marquis de~Sade!} But I {\em did} see it.
-\end{document}
-
-In the nested emphasis, \emph had to be given for each word separately
-so the spaces between could stretch and break into lines.  Even the
-discretionary hyphen (\-) in `Persecution' had to be outside the braces,
-but the hyphen in `Direction' was just fine because it was not in nested
-braces. The same applies to other special commands like \  and ~. Also,
-the spaces are printed with only a single underline because they are
-outside the nested \emph commands.  This example really illustrates that
-ulem does not handle nested emphasis very well!  Nevertheless, it is fine
-for simple things.
-
-Underlining can also be done according to \uline{this text}. To use this
-type of underlining, but have \em still produce italics, put the command
-\normalem in the preamble of the document or load ulem with
-\usepackage[normalem]{ulem}.
-
-Some variations on underlining are provided, including a wavey underline
-(\uwave{under-wave}), double underlines (\uuline{two lines under this}),
-a line through text rather than under it (\sout{strike out}), and text
-crossed-out with /////// (\xout{cross out, X out}).  You can define your
-own styles following the examples provided.  The definition should be
-something like:
-
-\newcommand\command{\bgroup \markoverwith{something}\ULon}
-
-The "something" can be as simple as a single character, or as complex as
-you can keep track of.
-
-The various underlining commands are essentially textual, and will not
-work quite the same in math mode.  But since some font commands, like \bf,
-serve both for text and math, math mode is handled (in an approximate way).
-The performance in math mode is somewhat different from in text: there will
-be no line breaks or stretching in the underlined text, and the vertical
-positioning may not be right.  The results should be best for \uline,
-\uwave, \uuline, and any other truly UNDER-line you define.
-
-Any type of underlining can be substituted for any font-selection command
-by issuing a proper \useunder declaration:
-
-\useunder{\underlinecommand}{\fontdeclaration}{\fontcommand}
-
-e.g., \useunder{\uuline}{\bfseries}{\textbf} gives a double underline
-instead of bold face in LaTeX.  The commands \normalem and \ULforem switch
-underlining for \em off and on, respectively, and so do the \usepackage
-options [normalem] and [ULforem]. There is also the \usepackage style
-option [UWforbf] to replace boldface with a wavey underline.
-
-UWforbf does handle \bf in math mode, but it doesn't work in section titles,
-unfortunately, because the titles are not delimited by explicit braces when
-printed by the \section command.  For the present version, the \bfseries
-command still produces bold face, but \bf makes an under-wave. To get under-
-waved section titles you can do
-
-\renewcommand\@seccntformat[1]{\uwave{\csname the#1\endcsname}\hskip 1em}
-
-and later specify \section[...]{\uwave{...}}.
-
-In plain TeX there is no \textbf so you should use \useunder{\UWave}{\bf}{}.
-You can even skip a step and define the underline or overprint with \useunder:
-\useunder{\bgroup\markoverwith{!}\ULon}{\sf}{}
-
-Some commands, such as \\ and \hskip are given special treatment, but 
-others (like \marginpar) are not.  Support for others can be added by 
-assigning special meanings in the token register \UL@hook.  (In LaTeX do 
-\addto@hook\UL@hook{\let\command\ULversion}.)  The UL versions of commands 
-should be modelled on \UL@hskip or \UL@cr, and should include the test 
-"\ifx\ \LA@space".  For example, support for "\marginpar" is added through
-the hook mechanism.
-
-All the underlining commands are robust in LaTeX.
