%\begin{abstract}
%\noindent
% The \microtype\ package provides a \LaTeX\ interface to the micro-typographic
% extensions that were introduced by \pdftex\ and have since also propagated to
% \luatex\ and \xetex: most prominently, character protrusion and font expansion,
% furthermore the adjustment of interword spacing and additional kerning, as
% well as hyphenatable letterspacing (tracking) and the possibility to disable
% all or selected ligatures.
% These features may be applied to customisable sets of fonts, and all
% micro-typographic aspects of the fonts can be configured in a straight-forward
% and flexible way. Settings for various fonts are provided.
%
% Note that character protrusion requires \pdftex\ (version~0.14f or later),
% \luatex, or \xetex\ (at least version~0.9997).
% Font expansion works with \pdftex\ (version~1.20 for automatic expansion)
% or \luatex.
% The package will by default enable protrusion and expansion if they can safely
% be assumed to work.
% Disabling ligatures requires \pdftex\ ($\geq$\,1.30) or \luatex, while the
% adjustment of interword spacing and of kerning only works with \pdftex\ ($\geq$\,1.40).
% Letterspacing is available with \pdftex\ ($\geq$\,1.40) or \luatex\ ($\geq$\,0.62).
%
% The alternative package \letterspace, which also works with plain \TeX,
% provides the user commands for letterspacing only, omitting support for all
% other extensions (see section~\ref{sec:lettersp}\ifcodedoc\space of the User manual\fi).
%
