             is a bad idea, because \TeX{} doesn't distinguish between terribly bad and
             preposterously horrible lines.  Indeed, a tolerance of 10000 encourages \TeX{} to
             concentrate all the badness in one place, making one truly unsightly line instead of
             two moderately bad ones, because a single ``write-off'' produces fewest total

             part of the paragraph.)  (2)~Three or more items are put at the end of the

             \code{parshape}=\metavar{number}, where the \metavar{number} is a positive integer~\(n\),

             between the baselines---say only half a point---can make a substantial difference
             in the appearance of the type, since it significantly affects the proportion of
             white to black.  On the other hand, if you are preparing a one-page document, you
             might want to give the baselineskip some stretchability, so that \TeX{} will help

\section{Information}

\code{\string\fontsizeinfo} --\fontsizeinfo{docsizeinfo}
At this point of the document, the font~size
and the line~spacing are \docsizeinfo*~(w/o~units).
For footnotes however, the current sizes are%
\footnote{This is the footnote where we get the sizes from.\fontsizeinfo{footsizeinfo}}
\footsizeinfo.

Next we show a comparison of different font sizes and line spacings
decorated with the results of \code{\string\fontsizeinfo}.

\section{Manual Italic Correction}

\paragraph{Text Mode.}

The italic correction of the current font is \the\fontdimen1\font/pt.

We demonstrate the effect of \code{\string\itcorr} with a pair of bookends:
uncorrected italics: \indicatewidth{\it X},
\TeX-corrected (\code{\string\/}): \indicatewidth{\it X\/},
and \code{\string\itcorr\{7\}}: \indicatewidth{\it X\itcorr{7}}.

Correction~0: \indicatewidth{\itcorr*{0}};
corr.~3: \indicatewidth{\itcorr{3}}, \indicatewidth{\itcorr*{3}} (starred);
corr.~\textminus6: \indicatewidth{\itcorr{-6}}.

\paragraph{Mathematical Mode.}

Uncorrected: \([f]\),
corrected: \([\itcorr{1} f\itcorr{1}]\)

Correction~0: \indicatewidth{\(\itcorr{0}\)};
corr.~3: \indicatewidth{\(\itcorr{3}\)};
corr.~\textminus6: \indicatewidth{\(\itcorr{-6}\)}.

\section{Align Last Line}

\subsection{Last Line Ragged Left/Flush Right}

\Cref{ex:lastlineraggedleftpar} is a typical use of environment~\code{lastlineraggedleftpar}:
A narrow paragraph gets typeset with full justification
and put \code{\string\flushright} against the right margin as a whole.

The layout may look more coherent if the last lines is moved to the right margin, too.

\begin{exemplary}
  \flushright
  \caption[Justified -- flushright]
          {\begin{typoginspectpar}{justified-flushright}Typeset a justified paragraph flushright and let
           macro~\code{\string\lastlineraggedleft} shift the last line
           over to the right-hand side.\label{ex:lastlineraggedleftpar}\end{typoginspectpar}}

\subsection{Last Line Centered}

The situation shown in \cref{ex:lastlinecenteredpar} is
more widespread than \cref{ex:lastlineraggedleftpar}
because centered tables and figures are quite common.
Their caption parboxes are centered too,
which is where a centered last line might fortify the layout.

Another possible use of environment~\code{lastlinecenteredpar} are the final lines of chapters~--
in particular if the chapters' ends are marked with centered dingbats.

\begin{exemplary}
  \centering
  \caption[Typeset a justified paragraph that is centered.]
          {\lastlinecenteredpar
           Typeset a justified paragraph that is centered.
           This very caption uses \code{lastlinecenteredpar}
           to have its last line centered as well.
           Moreover, we put a nifty asterisk centered at the bottom of the sample text.

    \[g H = H g \quad \text{for all} \enspace g \in G.\]

  Follow-up paragraph after and outside of the \code{vtiebotdisp}-environment.

    In this example we need a paragraph that follows the displayed math.
    So, we have to type some more text here
    to be able to demonstrate the action of the environment.
