%
% The ulem package provides various types of underlining that can stretch
% between words and be broken across lines in LaTeX or plain TeX.
% In LaTeX ulem replaces italics with underlining in \em-phasized text.
% It is most suitable for simple text such as {\em ibid.} or \emph{\LaTeX:
% A Document Preparation System} that may need to be underlined in a
% manuscript submitted for publication. A declaration of \normalem (or
% the \usepackage option "normalem") restores the normal \em behavior.
%
% Full instructions appear in ulem.ltx (ulem.pdf). 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 //////.
% \dashuline{dashing} dash underline
% \dotuline{dotty} dotted underline
%
% {\em phasized\/} | In LaTeX, by default, these are underlined; use
% \emph{asized} | \normalem or [normalem] to restore italics
% \useunder{\uwave}{\bf}{\textbf}
% use wavy underline in place of bold face
% Use \markoverwith for defining new types of underlining.

% That concludes the basic underlining. To put various other objects

% that `pixel' size = box size. Note that we generally need \leaders
% (not \cleaders) for text, because an underline will be a patchwork
% of small \leaders, and the characters must stay in registration.
% However, we "hook" the leaders command so specific applications can
% reassign it (\let\ULleaders\xleaders or \let\ULleaders\cleaders).

% Previous bug-finders: Esther Hu (\hfill in plain); Lones Smith (\tt\-);
% Steve Anderson (\ooalign accents); Thanassi Protopapas ( { in tables).
% The bug finders' fee is now $0.00; it will double for each new bug found.
% Version (identified by year)
% 1994:
% Many changes! Notably: LaTeX2e options and \emph. Nesting works (somewhat).
% Behavior with inner braces is more consistent (not stripped). \useunder.
% Better underwave (using lasy6). Special underlines are not commented out.
% patch 1995: fix \UL@swender to work in {tabular}; make hyphenation join
% well; crude math support; eliminate \@clb
% 1996: use "\csname ProvidesPackage\endcsname", tidying.
% 1997: fix \\ when LaTeX changed; remove extra overlap in putbox.
% 2000: hook (and marginpar)
% 2004: Fix spacing in \uwave and \xout. \ULleaders hook.
% 2009: Accept \par in argument (\long)
% 2010: Include \dotuline and \dashuline, typeset documentation, add \UL@setULdepth
% 2011: Change \dimen@ to \UL@height
% 2012: Removed \let\par garbage
% 2017: Remove \makerobust
% 2019: Handle \ULdepth better. Some tweaks.
