 \maketitle

 The Computer Modern font family has a sans serif typeface. However, compared to the serif typeface, it is incomplete: there are no sans serif small caps or math fonts. Furthermore, the bold slanted font is not available as an outline font.
 This leads to highly unsatisfactory typography of documents that use sans serif for the body text.
 
 
 The \textsf{sansmathfonts} package provides these ``missing'' fonts. Most of the usefulness of the package is in the fonts; \texttt{sansmathfonts.sty} is a small package providing \LaTeX\ support. To use it, simply say \texttt{\char`\\usepackage\char`\{sansmathfonts\char`\}} in the document preamble.
 
-This will redefine the document's default sans serif font family from \textsf{cmss} to \textsf{xcmss}; this will make the \textsf{\textbf{\textit{bold slanted}}} and \textsf{\textsc{Caps and small caps}} fonts available via normal \LaTeX\ font commands (\verb|\textbf|, \verb|\textit| and \verb|\textsc|). If you additionally load Harald Harder's \textsf{slantsc} package, this will make \textsf{\textit{\textsc{slanted caps and small caps}}} available.
+In the default (OT1) text font encoding, and also in the T1 and U font encodings, this will redefine the document's default sans serif font family from \textsf{cmss} to \textsf{xcmss}; this will make the \textsf{\textbf{\textit{bold slanted}}} and \textsf{\textsc{Caps and small caps}} fonts available via normal \LaTeX\ font commands (\verb|\textbf|, \verb|\textit| and \verb|\textsc|). If you additionally load Harald Harder's \textsf{slantsc} package, this will make \textsf{\textit{\textsc{slanted caps and small caps}}} available.
 
 This will also switch the math fonts to sans serif:
 \[\Im \mathop{\mathrm{exp}}(i\omega)=\sin(\omega) \]

 The math fonts differ slightly from Knuth's standard sans serif fonts. Specifically, for ease of reading I have chosen to put the serifs back on the uppercase I, Pi and~Xi:
-\[I\quad\mathrm{I}\quad\mathbf{I}\quad\bm{I}\quad
-\mathit{\Pi}\quad\Pi\quad\mathbf{\Pi}\quad
-\mathit{\Xi}\quad\Xi\quad\mathbf{\Xi}\quad
-\text{and not\quad \textsf{I\quad \char5\quad\char4}}\]
-\textsf{Sans serif Is outside of math mode} still have no serifs unless the package option \texttt{[I]} is used; note that this option is incompatible with the T1 encoding.

+\section{Package options}
+
+\begin{itemize}
+\item \texttt{[I]} The \texttt{[I]} package option puts the serifs back on the capital I even in text mode. This option only works with the OT1 and U font encodings.
+\item \texttt{[onlymath]}, \texttt{[nottext]}. These options provide sans serif math but do not change the text sans serif font.
+\item \texttt{[onlytext]}, \texttt{[notmath]}. These options provide sans serif text fonts and improve the behavior of \texttt{\char`\\mathsf} but do not change the default math font from roman to sans serif. You can get a similar effect by not using the \textsf{sansmathfonts} package and using the line \texttt{\char`\\renewcommand\char`\{\char`\\sfdefault\char`\}\char `\{xcmss\char`\}}
+or
+\texttt{\char`\\renewcommand\char`\{\char`\\sfdefault\char`\}\char `\{cmsmf\char`\}}
