+\begin{document}

+\maketitle
+
+\section{Commands:}
+
+
+
+\begin{labeling}{\cmd{\cancelto}\marg{value}\marg{expression}}
+\item[\cmd{\cancel}] draws a diagonal line (slash) through its argument.
+\item[\cmd{\bcancel}] uses the negative slope (a backslash).
+\item[\cmd{\xcancel}] draws an X (actually \cmd{\cancel} plus \cmd{\bcancel}).
+\item[\cmd{\cancelto}\marg{value}\marg{expression}] draws a diagonal arrow through the \meta{expression}, pointing to the \meta{value}.
+\end{labeling}
+%
+The first three work in math and text mode, but \cmd{\cancelto} is only
+for math mode.
+The slope of the line or arrow depends on what is being cancelled.  
+
+
+\section{Options:}
+
+Bt default, none of these commands affects the horizontal spacing, 
+so they might over-print neighboring parts of the formula (or text).
+They do add their height to the expression, so there should never be 
+unintended vertical overlap.  There is a package option \texttt{[makeroom]} to 
+increase the horizontal spacing to make room for the cancellation value.  
+
+If you use the color package, then you can declare
+%
+\begin{verbatim}
+  \renewcommand{\CancelColor}{<color_command>}
+\end{verbatim}
+%
+and the cancellation marks will be printed in that color (e.\,g., \cmd{\blue}).
+However, if you are using color, I recommend lightly shaded blocks rather
+than diagonal arrows for cancelling.
+
+The option \texttt{[thicklines]} asks for heavier lines and arrows. This may be
+useful when the lines are colored a light shade.
+
+\begin{samepage}
+  The size (math style) of the \cmd{\cancelto} value depends on package options 
+  according to this table:
+  % 
+  \begin{center}
+    \small
+    \begin{tabular}{@{}llll@{}}
+      \toprule
+      \textbf{Current style}   & \textbf{\texttt{[samesize]}} & \textbf{\texttt{[smaller]}} & \textbf{\texttt{[Smaller]}} \\
+      \midrule
+      \cmd{\displaystyle}      & \cmd{\displaystyle}          & \cmd{\textstyle}            & \cmd{\scriptstyle}          \\
+      \cmd{\textstyle}         & \cmd{\textstyle}             & \cmd{\scriptstyle}          & \cmd{\scriptstyle}          \\
+      \cmd{\scriptstyle}       & \cmd{\scriptstyle}           & \cmd{\scriptscriptstyle}    & \cmd{\scriptscriptstyle}    \\
+      \cmd{\scriptscriptstyle} & \cmd{\scriptscriptstyle}     & \cmd{\scriptscriptstyle}    & \cmd{\scriptscriptstyle}    \\
+      \bottomrule
+    \end{tabular}
+  \end{center}
+  % 
+  (``\texttt{smaller}'' is the default behavior.  It gives textstyle limits in 
+  displaystyle, whereas ``\texttt{Smaller}'' gives scriptstyle limits.)
+\end{samepage}
+
+This package is provided without guarantees or support.  Drawing slashes
+through math to indicate ``cancellation'' is poor design.  I don't recommend
+that you use this package at all.
