+############ A BRIEF DESCRIPTION OF THE FONT ############
+###########################################################################
+
+TeX Gyre Termes Math is a math companion for the TeX Gyre Termes family
+of fonts (see http://www.gust.org.pl/projects/e-foundry/tex-gyre/) in
+the OpenType format.
+
+The math OTF fonts should contain a special table, MATH, described in the
+confidential Microsoft document "The MATH table and OpenType Features
+for Math Processing". Moreover, they should contain a broad collection
+of special characters (see "Draft Unicode Technical Report #25.
+UNICODE SUPPORT FOR MATHEMATICS" by Barbara Beeton, Asmus Freytag,
+and Murray Sargent III). In particular, math OTF scripts are expected
+to contain the following scripts: a basic serif script (regular, bold,
+italic and bold italic), a calligraphic script (regular and bold),
+a double-struck script, a fraktur script (regular and bold), a sans-serif
+script (regular, bold, oblique and bold oblique), and a monospaced script.
+
+The basic script is, obviously, TeX Gyre Termes. Symbols, namely,
+calligraphic, double struck, Greek, sans serif bold Greek, and Hebrew,
+were drawn from scratch. The main math component, that is, the math
+extension, was also programmed from scratch.
+
+Some scripts, however, are borrowed from other fonts (the current
+selection, however, may be subject to change):
+
+ * The fraktur alphabets (regular and bold) is excerpted
+ from the Leipziger Fraktur replica by Peter Wiegel
+ ( http://www.peter-wiegel.de/Leipzig.html )
+ with the kind permission of the author.
+
+ * The sans serif alphabets (regular, oblique, bold, and
+ bold oblique) are excerpted from TeX Gyre Heros
+ http://www.gust.org.pl/projects/e-foundry/tex-gyre/heros
+ (actually, the sans serif bold Greek symbols are based
+ on TeX Gyre Heros Greek alphabet).
+
+ * The monospaced alphabet is excerpted from TeX Gyre Cursor
+ http://www.gust.org.pl/projects/e-foundry/tex-gyre/cursor
+
+Note that the members of all the mentioned alphabets, except
+the main roman alphabet, should be considered symbols, not letters;
+symbols are not expected to occur in a text stream; instead,
+they are expected to appear lonely, perhaps with some embellishments
+like subscripts, superscripts, primes, dots above and below, etc.
+
+To produce the font, MetaType1 and the FontForge library were used:
+the Type1 PostScript font containing all relevant characters was
+generated with the MetaType1 engine, and the result was converted
+into the OTF format with all the necessary data structures by
+a Python script employing the FontForge library.
+
+Recent changes (ver. 1.502 --> ver. 1.543) comprised
+mainly interline settings in OTF tables (HHEA and
+OS/2) and the correction of the unicode slots assigned to
+contour integrals (glyphs `clockwise contour
+integral', u+2232, and `anticlockwise contour
+integral', u+2233, used to have swapped slots).
+
+ * * *
+
+The TeX Gyre Math Project was launched and is supported by
+TeX USERS GROUPS (CS TUG, DANTE eV, GUST, NTG, TUG India, TUG, UK TUG).
+Hearty thanks to the representatives of these groups and also
+to all people who helped with their work, comments, ideas,
+remarks, bug reports, objections, hints, consolations, etc.
