-This is the mathdots package, version 0.8.
-
-This package changes the basic LaTeX and plain TeX commands \ddots and
-\vdots so that they properly change size when font sizes change, and
-when they are used in superscripts and subscripts. It also adds the
-command \iddots ()for inverse diagonal dots) which slants the opposite
-way from \ddots.
-
-In addition, if it detects AMSLaTeX (or AMSTeX in plain TeX) it defines
-improved versions of the \dddot and \ddddot commands that place three
-and four dots on a math symbol (similar to the math accent commands \dot
-and \ddot). These also are arranged to change size correctly and some
-placement bugs are corrected.
-
-Other (minor) improvements: the commands \vdots, \ddots and \iddots
-select the dot from the math fonts instead of the text fonts, so they
-always match math punctuation dots. The \dddot and \ddddot commands
-select the accent dot (same one placed by \dot).

+%
+% \DescribeMacro{\MDoprekern}
+% \DescribeMacro{\MDodotkern}
+% \DescribeMacro{\MDopostkern}
+% Different math fonts have different metrics for the \cs{dot} and
+% \cs{ddot} accents. If you use a math font family other than the CM
+% fonts, you can adjust the positioning and spacing of the the dots in
+% \cs{dddot} and \cs{ddddot} to better match the spacing in \cs{ddot}
+% with the following length commands: \cs{MDoprekern}, \cs{MDodotkern} and
+% \cs{MDopostkern}. These adjust the space before the first dot, between
+% the dots and after the last dot, respectively. They are in units of
+% \texttt{mu}, which is $1/3$ the size of the space made by \cs{,}.
+% Reducing the first and/or increasing the last one cause the dots to be
+% shifted left. Reducing the middle one causes the dots to be closer
+% together. As there is usually a bit of white on either side of the dot
+% character, these usually have to be given negative values (so ``reduce''
+% means ``make more negative''). The defaults for the CM fonts are
+% accomplished by the commands
+% \begin{verbatim}
+%   \MDoprekern=0mu
+%   \MDodotkern=-1.3mu
+%   \MDopostkern=-1mu \end{verbatim}
+% I have found that the \prog{mathptmx} package (Times fonts in text and
+% math) benefits from changing these via the following commands
+% \begin{verbatim}
+%   \MDoprekern=-1mu
+%   \MDodotkern=-2mu
+%   \MDopostkern=0mu \end{verbatim}
+% \cs{MDoprekern}, \cs{MDodotkern}, and \cs{MDopostkern} were made
+% user-accessible commands in version 0.9.
+%
+% \DescribeMacro{\MDoddots}
+% \DescribeMacro{\MDovdots}
+% \DescribeMacro{\MDoiddots}
+% \DescribeMacro{\MDodddot}
+% \DescribeMacro{\MDoddddot}
 % In \LaTeX{}, all these commands have been made robust as of version 0.6.
+% On the chance that some later loaded package changes things, the \MD{}
+% versions can be obtained with \cs{MDoddots}, \cs{MDovdots},
+% \cs{MDoiddots}, \cs{MDodddot} and \cs{MDoddddot} (as of version 0.9).
