% \noindent
% The default CM math fonts used by \TeX\ do not include upright
% lowercase Greek characters, and most alternative math font sets don't,
% either.  (There are math fonts providing \emph{only} an upright
% Greek alphabet, but that's a different story.) 
% However, mathematical constants such as $\pi = 3.14\dots$ 
% are sometimes required to be typeset in roman (i.e., upright) style,
% or one may need upright Greek to designate elementary particles.
%
% As a workaround, 
% the \LaTeX{} package \textsf{upgreek} makes the upright
% Greek characters from the `Euler' or `Adobe Symbol' typefaces available
% as math symbols.  The lowercase letters are named  
% +\upalpha+, +\upbeta+ etc., whereas +\Updelta+, +\Upgamma+ etc.\ create
% upper case. 
%
% Just like +\alpha+, +\beta+ etc., these symbols work only in math
% mode, and their size is properly adjusted, when they are used in 
% superscripts, subscripts or fractions.
%
% At first sight, providing also the uppercase letters seems pointless,
% since +\Delta+, +\Gamma+, etc.\ are also upright by default.  However,
% it may be useful to have all upright Greek letters available in the
% same style.  Note that the uppercase letters were intentionally
% \emph{not} named +\upDelta+ etc., so as not to clash with other
% existent macro packages.
%
% The typeface is selected through a package option, so you can
% choose what blends best with the other fonts used in your document:
% \begin{description}
%   \item[{\mdseries\ttfamily [Euler]}] Euler Roman/Bold (default)
%   \item[{\mdseries\ttfamily [Symbol]}] Adobe Symbol
%   \item[{\mdseries\ttfamily [Symbolsmallscale]}] Adobe Symbol, scaled down to 90\% of
%   its natural size. (New feature in version 2.0\,!)
% \end{description}
% 
% Note that +\upmu+ should normally \emph{not} be used as the prefix
% for physical units, meaning $10^{-6}$.  The mu symbol to be used there
% is to be taken from the \emph{text} font, and
% most Latin text fonts do actually include a suitable Greek mu,
% which can be accessed as +\textmu+.
% Most likely -- depending on the encoding of your text fonts -- you
% need to load the package \textsf{textcomp} for this purpose.
% If, however, there is no mu in your text fonts,
% using +\upmu+ is still better than nothing.
% See also the \textsf{gensymb} package, which is distributed from the same
% CTAN directory than \textsf{upgreek}:  It provides a command for `micro' 
% that works in both text and math mode and uses either +\textmu+ or +\upmu+, 
% depending on the available character sets.
