+% This small package comes essentially verbatim from the following |c.t.t.| post by Donald Arseneau: \url{http://groups.google.com/group/comp.text.tex/msg/f207c7535810d2c1}.\footnote{I am distributing this package with the LPPL license, while I assume that Donald's original code to be in the public domain. This license stuff can be a bit messy sometimes.}
+% \end{quote}
+%
+% Consider the standard output of a subscript with and without a superscript above:
+% \begin{center}
+% \usebox\wspr
+% \end{center}
+% The second $n$ is lower due to \TeX's default of jiggling the space when there are both superscripts and subscripts attached to a math symbol.
+%
+% In some circumstances, this isn't particularly desirable; this package adjusts \LaTeX's behaviour to unify the position of the subscript in both cases:
+% \begin{center}
+% \Huge $M_n$ $M_n'$
+% \end{center}
+%
+% Notice that to compensate for the higher subscript, the superscript position is slightly raised. The |[low-sup]| package option will suppress this change to the height of the superscripts.

+% \section{Don's code}
+%
+% \textit{The comments that follow are Donald's. His out-commented diagnostic messages have been removed for clarity.}
+%
+% Set the fontdimen parameters for subscript and superscript position
+% so that |C_2H_5^+| has both subscripts at the same vertical position.
+% Do this by actually comparing |H_2| with |H_2^+| and adjusting the font's
+% sub-lowering (16, 17) by half the difference and setting the super-
+% raising (13, 14, 15) to the matching position. The settings (for
+% all three fonts t,s,ss) are determined once per text-font-size and
+% stored in the macro |\dch@sizet<size>| (e.g.\ |\csname dch@sizet12\endcsname|).
+% Since some specific fonts are used in different roles at different
+% text-font-sizes, the original (tfm) settings for each particular font
+% are saved in a macro |\dch@size<size>| (no "t") before they are changed
+% for the first time. When that font appears in a different role for
+% another text-font size, those original settings are restored first
+% before making changes.
