############          A BRIEF DESCRIPTION OF THE FONT          ############
###########################################################################

TeX Gyre Schola Math is a math companion for the TeX Gyre Schola 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 Schola. Greek symbols are based on Theano Modern font
(http://www.thefreewindows.com/2949/old-standard-unicode-greek-polytonic-font/)
by Alexey Kryukov with the kind permission from the author to use his work
with the GFL licence. The double struck and calligraphic scripts were created
from scratch as well as the math extension, i.e., the main component of the font.

Other scripts, however, are borrowed from other fonts (the current
selection, however, may be subject to change):

  * the fraktur script is excerpted from the renowned Euler family
    (http://en.wikipedia.org/wiki/AMS_Euler);

  * the sans serif alphabets are excerpted from another renowned font,
    Lato by /Lukasz Dziedzic (http://www.latofonts.com/) also with the
    kind permission from the author to use his work
    with the GFL licence;

  * and finally, the monospaced alphabet is taken from TeX Gyre Cursor
    (see http://www.gust.org.pl/projects/e-foundry/tex-gyre/).

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. 1.526 --> ver. 1.533) comprised mainly
interline settings in OTF tables (HHEA and OS/2).
