-% The \pkg{mathscinet} packages provides definitions for certain
-% commands that occasionally occur in bibliographic data exported
-% from MathSciNet and that are not provided by \latex/.
-%
-% \textbf{Warning:} Although the macros provided in this package
-% are probably acceptable if all you need to do is format an entry
-% downloaded from MathSciNet, they should probably not be used for
-% other purposes. In general, if you are trying to typeset
-% material in any languages that require these characters, you are
-% better off using specialized fonts and encodings for those
-% languages.

-% When putting together an accented character from bits and pieces,
-% the |\spacefactor| of the base character often gets lost in the
-% shuffle. We use essentialy the same technique as |\add@accent|

-% \end{macrocode}
-% \end{macro}
-%
-% \begin{macro}{\@underaccent}
-% This is perhaps the most interesting macro in this package (which
-% admittedly isn't saying much). It attempts to convert a character
-% (usually one of the standard above-letter diacritics like~\"{})
-% into an underhanging diacritic (like~\dudot{\hbox to
-% .5em{\hss}}). This is similar in spirit to the way that the
-% \enc{OT1} \cn{b} command converts a macron into a bar-under
-% accent, or the way that \cn{d} converts a period into an
-% underhanging dot. However, the technique used here is a little
-% more complicated and, hopefully, a little more general, in the
-% sense of requiring fewer ad-hoc parameters. It only contains one
-% magic constant (.2\,ex), which seems to provide reasonable
-% results for all of the Computer Modern fonts.
-%
-% The basic algorithm is as follows:
-%
-% \begin{enumerate}
-%
-% \item
-% Create a box~$B$ containing the base character at its natural
-% height, depth, and width.
-%
-% \item
-% Create a box~$d$ consisting of the diacritic centered in a space
-% equal to the width of~$B$.
-%
-% \item
-% Lower box~$d$ by the sum of its height (to bring the top of~$d$
-% down to the baseline) plus the depth of $B$ (to bring the top
-% of~$d$ down to the bottom of~$B$) plus .2\,ex (to provide the
-% spacing between the bottom of the letter and the top of the
-% diacritic). Call the new box~$d'$.
-%
-% \item
-% Create a new box~$C$ by superimposing boxes $B$ and~$d'$.
-%
-% \item
-% If the height of~$d$ was greater than 1\,ex, reset the depth of
-% box~$C$ to the sum of the depth of~$B$ and 1\,ex less than the
-% height of~$d$. (See the appendix for a discussion of this step.)

-% \section*{\raggedright Appendix: Plumbing the depths of
-% underhanging diacritics: Notes on the magic constant 0.2\,ex and
-% an exegesis of certain obscure corners of the \cn{@underaccent}
-% macro}
-%
-% \tex/ assumes that a combining accent can be superimposed
-% directly on top of any character whose height is 1\,ex. If the
-% actual height of the base character differs from 1\,ex, the
-% accent is shifted up or down to maintain the same vertical
-% separation. Put another way, subtracting 1\,ex from the height
-% of a combining accent tells us how much a character's height is
-% increased when that accent is added. Call this
-% distance~$\delta$.
-%
-% This distance can be analyzed into two pieces: $\delta = \sigma +
-% \eta$, where $\sigma$ is the separation between the top of
-% the base character and the \emph{bottom} of the accent, and
-% $\eta$ is the height of the bounding box of the accent.
-%
-% If we now consider moving the accent to the bottom of a
-% character, we have a new relation $\delta' = \sigma' + \eta$,
-% where $\sigma'$ is the distance between the bottom of the base
-% and the \emph{top} of the accent, and $\delta'$ is the amount by
-% which the depth of the base character is increased.
-%
-% If the placement of the underhanging version of an accent were
-% strictly symmetrical with the overhanging version, then we would
-% have $\sigma' = \sigma$ and thus $\delta' = \delta$. However, the
-% placement is not symmetric since for aesthetic reasons we have
-% chosen to set $\sigma' = .2\,\mathrm{ex}$, which seems in general
-% to be a little less than the corresponding~$\sigma$.
-% Unfortunately, this means we can't calculate~$\delta'$ accurately
-% since there is no way to deduce $\eta$ (or, equivalently,
-% $\sigma$) from the font metric information available to us
-% within~\TeX.\footnote{By exploiting symmetries present in some
-% fonts, one can calculate $\eta$ for some of the accents in those
-% fonts, but this doesn't help us much since both $\sigma$
-% and~$\eta$ vary between accents.}
-%
-% This leaves us in a bit of a bind, since it means there is no way
-% to calculate the depth accurately. In despair, I've decided just
-% to pretend that $\delta' = \delta$ for now.
