+\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.
+
+This will also switch the math fonts to sans serif:
+\[\Im \mathop{\mathrm{exp}}(i\omega)=\sin(\omega) \]
+If you use symbols from the \textsf{amsfonts} or \textsf{esint} packages, they will also be replaced by appropriate sans serif versions:
+\[\ointclockwise \quad \mho \quad \hbar\]
+By default, the commands \verb|\mathrm| and \verb|\mathsf| both produce sans serif text. To get serifed roman text, use the command \verb|\mathserif|:
+\[\mathrm{mathrm}\quad\mathsf{mathsf}\quad\mathserif{mathserif}\]
+\textsf{sansmathfonts} knows about the \textsf{beamer} document class and will automatically use \textsf{beamer}'s \texttt{professionalfonts} theme.
+
+
+If you prefer roman math fonts, either use the \texttt{[notmath]} package option, or don't use the package at all; instead use the line \texttt{\char`\\renewcommand\char`\{\char`\\sfdefault\char`\}\char `\{xcmss\char`\}}
+in the document preamble.
+
+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.
+
+
+Feedback is appreciated and may be sent to \texttt{origamist@gmail.com}.

+\section{Files in this package}\label{sec:files}
+
+109 of the new fonts listed in \autoref{sec:fonts} come in three files each: the \TeX\ Font Metric files (extension \texttt{.tfm}), the Type 1 font file (extension \texttt{.pfb}), and Metafont source file (extension \texttt{.mf}).
+
+The 9 \textsf{cmssxi} and \textsf{cmssbx} fonts come as \texttt{.pfb} files only, as the MetaFont sources are already part of the \TeX\ Live distribution (see also the \textsf{sauter} package at \texttt{\href{http://www.ctan.org/tex-archive/fonts/cm/sauter} {http:/\slash www.ctan.org\slash tex-archive\slash fonts\slash cm\slash sauter}}).
+
+The 28 \textsf{cmsmf} fonts are almost identical to their \textsf{cmss} counterparts. Thus, these fonts are provided as \emph{virtual} fonts, and so come in five parts: the virtual font file (\texttt{cmsmf.vf}), the \TeX\ Font Metric file (\texttt{cmsmf.tfm}), and the font \textsf{cmsmfIPiXi} containing only the altered letters \cmsmf{I}, \cmsmf{\char4} and \cmsmf{\char5} (and \cmsmf{\textsc{i}}, in the small caps fonts); this font comes as MetaFont source (\texttt{cmsmfIPiXi.mf}), \TeX\ font metric (\texttt{cmsmfIPiXi.tfm}) and Type 1 font (\texttt{cmsmfIPiXi.pfb}).
+
+In addition, this package should come with the following 29 supplementary Metafont source files:
+
+\begin{itemize}
+\item \texttt{eczi.mf}
+\item \texttt{eczo.mf}
+\item \texttt{eczx.mf}
+\item \texttt{eczz.mf}
+\item \texttt{sans-amsya.mf}
+\item \texttt{sans-amsyb.mf}
+\item \texttt{sans-asymbols.mf}
+\item \texttt{sans-bigdel.mf}
+\item \texttt{sans-bigint.mf}
+\item \texttt{sans-bigop.mf}
+\item \texttt{sans-bsymbols.mf}

+\item \texttt{sans-sym.mf}
+\item \texttt{sans-symbol.mf}
+\item \texttt{sans-xbbold.mf}
+\item \texttt{sansfontbase.mf}
+\end{itemize}
+
+This package should also come with the following 11 \LaTeX\ Font Definition files:
+
+\begin{itemize}
+\item \texttt{omlcmssm.fd}
+\item \texttt{omscmsssy.fd}
+\item \texttt{omxcmssex.fd}

+\item \texttt{ussesint.fd}
+\item \texttt{ussmsa.fd}
+\item \texttt{ussmsb.fd}
+\item \texttt{uxcmss.fd}
+\end{itemize}
+
+Finally, it should come with the font map file, LaTeX package, and documentation:
+
+\begin{itemize}
+\item \texttt{sansmathfonts.map}
+\item \texttt{sansmathfonts.sty}
+\item \texttt{sansmathfonts.tex}
+\item \texttt{sansmathfonts.pdf}
+\end{itemize}
+
+% The subfolders should contain:

+% Based on the Computer Modern source file bigdel.mf by D E Knuth.
+
+% Edited by Ariel Barton to produce better sans serif symbols
+
+% Date: 2013/03/22
+
+% This file contains series of large delimiters for math extension fonts.
+
+% The sizes are `{\tt\char`\\big}' (|2dh#|), `{\tt\char`\\Big}' (|3dh#|),
+% `{\tt\char`\\bigg}' (|4dh#|), and `{\tt\char`\\Bigg}' (|5dh#|),
+% followed in most cases by an extensible character that can grow
+% arbitrarily large in |dh#| steps,
+% where |dh#| is 60\% of the font design size.
+% (For example, a 10-point font will have large delimiters in sizes
+% 12$\,$pt, 18$\,$pt, 24$\,$pt, 30$\,$pt, 36$\,$pt, 42$\,$pt, etc.)
+
+% Character codes \0000--\0105 and \0150--\0177 are generated.

+% Based on the Computer Modern source file symbol.mf by D E Knuth.
+
+% Edited by Ariel Barton to produce better sans serif symbols
+
+% Date: 2013/03/22
+
+% This file defines the symbols of a \TeX\ math symbol font.
+% Character codes \0000--\0100 and \0133--\0177 are generated.
+
+% (Improvements to Knuth's original characters were worked out in 1982
+% by Ronald F. Whitney and other members of
+% the American Mathematical Society.)
+
+% Italic corrections have not been computed for most of these characters,
+% since they are generally not slanted.
