+% the characters in the list will not only inherit the protrusion of the base character,
+% but will be additionally protruded by the result of
+% |charwidth(|\meta{inheriting character}|)|$-$|charwidth|\allowbreak|(|\meta{base character}|)|:

+% the accent before the `H' would be fully protruded into the left margin,
+% while the stem of the `T' would be aligned with that of the `I' if at either margin.
+% This feature is especially useful for Greek typography, where capital letters
+% at the beginning of a line should be placed as if they had no accent (the `H' in
+% the example above).
+% Base characters may have both unprefixed and prefixed inheritance lists;
+% characters in the latter will be implicitly added to the corresponding unprefixed one.
+% Inheriting characters may appear in both `|(l)|' and `|(r)|'-prefixed lists at the
+% same time, whereas lists prefixed with `|(l)|' or `|(r)|' and those prefixed with
+% `|(lr)|' are mutually exclusive.

+%   \footnote{Possibly because \TeX\ tends to look through its gastro-intestinal tract.}
+% \eg, in |itemize| or |tabular| environments.

+% protrude as if it were located at a normal outer  margin:
+%

+% You may also just say \cs{leftprotrusion} (without an argument), and

+% adding protrusion on its left hand side.
+% For instance, you could add this command to tabular cell definitions
+% (using the \pkg{array} package):
+%\begin{verbatim}
+%\begin{tabular}{l>{\leftprotrusion}p{9cm}r}
+%\end{verbatim}
+% in order to get protrusion at the beginning of the |p| cell.
+%
+%\medskip
+%\Describe{Macro}{\rightprotrusion}{general text}
