% You can modify the appearance of grammars using three length parameters:
%
-% \begin{description} \def\makelabel{\hskip\labelsep\cmd}
+% \begin{description} \setdescriptionlabel{\cmd{#1}}
%
% \item [\grammarparsep] is the amount of space inserted between production
% rules. It is a rubber length whose default value is 8\,pt, with
%
% The following length parameters may be altered:
%
-% \begin{description} \def\makelabel{\hskip\labelsep\cmd}
+% \begin{description} \setdescriptionlabel{\cmd{#1}}
%
% \item [\sdstartspace] The length of the rule between the arrows which
% begin each line of the syntax diagram and the first item on the line.
%
% There's some extra cunningness here, because I'd like to be able to
% hyphenate after underscores usually, but not when there's another one
-% following. And then, because \env{tabbing} redefines |\_|, there's some
+% following. And then, because \env{tabbing} redefines |\-|, there's some
% more yukkiness to handle that: the usual |\@tabacckludge| mechanism doesn't
% cope with this particular case.
