+
+This is the README file for the LaTeX2e package `txgreeks',
+version 1.0, 2011/03/16
+
+\usepackage[option]{txgreeks} 
+
+Options:
+
+TeX:     lowercase Greek italic and uppercase upright (default),
+sloped:  synonym for TeX,
+ISO:     lowercase and uppercase italic,
+itgreek: synonym for ISO,
+upright: lowercase and uppercase upright,
+French:  synonym for upright,
+upGreek: uppercase Greek upright (default),
+itGreek: uppercase Greek italic.
+
+\usepackage{itGreek,upgreek} will give upright lowercase combined 
+with italic uppercase.
+
+Once the shapes have been decided the \other... prefix allows
+to use the alternative: for example if \alpha is in italic shape
+then \otheralpha will refer to the upright glyph.

+%  \begin{abstract}
+%    The TX Fonts \footnote{package
+%    \url{http://mirrors.ctan.org/help/Catalogue/entries/txfonts.html}}
+%    of \textsc{Young~Ryu} provide a very complete replacement for
+%    the default math fonts of \TeX{} and \LaTeX{}, containing all
+%    CM symbols and even all symbols from the \AmS{} fonts, and
+%    more.  In particular upright shapes for the Greek letters are
+%    available (they are necessary in French mathematical
+%    typography).  The |txgreeks| package\footnote{This document
+%    describes |txgreeks| version \fileversion\ (\filedate).}
+%    allows \LaTeX{} users who use the TX fonts to easily select
+%    the shapes (italic or upright) for the Greek lowercase and
+%    uppercase letters. This is compatible with using arbitrary
+%    text fonts in the document.
+%  \end{abstract}
+%
+%  \section{Features}
+%
+%  The shape of the Greek letters is decided according to the
+%  options passed to the package: |TeX| (=|sloped|, the default:
+%  lowercase italic and uppercase upright), |upright|
+%  (=|French|=|upgreek|, lowercase and uppercase upright), |ISO|
+%  (=|itgreek|, lowercase and uppercase italic), |itGreek| (italic
+%  uppercase) and |upGreek| (upright uppercase). Use both of
+%  |itGreek| and |upgreek| to get lowercase upright and uppercase
+%  italic.
+%
+%  The uppercase Greek letters are not taken from the TX roman
+%  font |txr| (`operators') but from either the alternate math
+%  italic font |txmia| (`lettersA', which in fact provides upright
+%  Greek in OML encoding), or from the math italic font |txmi|
+%  (`letters', where uppercase Greek is in italic shape). This
+%  means that if some other package redefines the `operators' font
+%  used in math (presumably to co\"incide with the `roman' font
+%  used for the document text), this will have no impact on the
+%  Greek uppercase letters. If some package modifies the `letters'
+%  font used in math (which typically is the font for Latin
+%  letters and lowercase Greek letters, and with |txgreeks| is
+%  also used for the italic uppercase Greek letters), then of
+%  course the glyphs will be from the new font. But the upright
+%  glyphs will still be from the TX Font |txmia| (`lettersA').
+%
+%  Following the model of the |fourier| package, the alternative
+%  shape of the Greek letters is accessible via the \cs{other...}
+%  prefix: \cs{otheralpha} will be upright if \cs{alpha} is
+%  italic, and vice versa. For the lowercase Greek letters there
+%  are also the macros ending in |up| (\cs{alphaup}, \dots) which
+%  are already defined by |txfonts|.
+%
+%  Regarding the uppercase letters, the package defines (replacing
+%  the |amsmath| definitions) \cs{varGamma}, etc\dots{} as synonyms for
+%  \cs{otherGamma}, etc\dots, but does not define additional
+%  macros \cs{Gammaup} as this was not done by the package
+%  |txfonts|. Use rather \cs{otherGamma} if
+%  necessary.\footnote{contrarily to |amsmath| we define the
+%  \cs{varGamma}, etc\dots{} to be of type \cs{mathalpha} so they
+%  obey, like the default \LaTeX{} \cs{Gamma}, etc \dots{} the math
+%  alphabet changing commands; however to access the bold glyphs I
+%  recommend using either the \cs{bm} command from the |bm|
+%  package or the \cs{boldsymbol} command from the |amsbsy|
+%  package and not \cs{mathbf} which by default will use the TX
+%  roman font |txr|.}
+%
+%  The package defines \cs{omicron}, \cs{otheromicron}, and
+%  \cs{omicronup}. But there is no upright omicron in the |txmia|
+%  font, so we have to use the construct |\mathrm{\omicron}| (this
+%  will a priori use the TX roman font |txr|).
+%
+%  It is not necessary to write |\usepackage{txfonts}| prior to
+%  |\usepackage{txgreeks}| as this is done by |txgreeks| itself,
+%  but for clarity of the \LaTeX{} source of the document to be
+%  typeset, this is highly recommended, as |txgreeks| does very
+%  minor things compared to |txfonts|.
+%
+%  Using |txgreeks| should be hopefully compatible with any
+%  package which is already compatible with |txfonts|.
